Quite a change of scenery, this planet Bunkum! Your sack person has been summoned via an incomprehensible means to this new world. The view is fantastic from the apex of the Needlepoint Peaks. It’s quite scenic, really, with plenty of bold mountaineers and picnics as far as the eye can see. And then there’s Newton, the bulbous-headed fellow who summoned your sack person.
Some might say the constant avalanches do put a damper on things from time to time, but Newton seems to know his way around. He needs your sack person to accompany him as he descends the mountainous region. What’s more, he has promised a present for you down below. What could it be?
Picnic among the Peaks
Follow the Leader!
Follow Newton’s lead to the right, and pop a series of six Prize Bubbles (Scarf Sticker, Jam Label Sticker, Pine Tree Sticker, Green Leaf Sticker, Tin Bucket Object, and Bouquet 3 Sticker) as you slide down the slippery ramp ahead.
Overcome the ice cube obstacles, and run headlong through a series of five Prize Bubbles. These bubbles offer the Straw Hat Costume, 50s Wavy Hair Costume, Sporting Club Jumper Costume, Pleated Skirt Costume, and White Heels Costume.
Continuing forward, press up on the left stick to duck through a picnic basket passage, and then press down on the left stick to emerge on the other side. Your sack person automatically pops a succession of Prize Bubbles to collect the Leather Strap Decoration, Bunny Body Sticker, Stitchem Arm Sticker, and Silver Belt Buckle Decoration.
Just ahead, three Prize Bubbles rise and fall with clockwork regularity. Leap up to pop each one and snag the Fox Head Sticker, Fox Tail Sticker, and Waist Coat Sticker.
After activating a Checkpoint, be sure to pop the Prize Bubble directly above it to get the Bunny Head Sticker. Hold down on the left stick and press 
to drop down the plush green steps and continue following Newton.
At the next location, two more Prize Bubbles that contain the Red Phonebox Sticker and Sliced Loaf Sticker await.
Follow Newton’s lead, automatically jumping up a step and into a background layer before popping out the other side and dropping down to the open area.
Try, Try Again
Two Prize Bubbles are suspended above some questionable-looking ice cubes. Too good to be true? Perhaps, but you know you want their delightful contents all the same! Doing so awards you the Bread Slice Sticker and Sealed Jar of Jam Object.
While leaping up to pop the bubbles, your sack person encounters a pair of jam jars plopping into place and purposely preventing progression. Pity. Your sack person naturally has no choice but to drop down another slick slide into the front layer. To the far left is a lone Prize Bubble. Burst it to add the Butter Decoration to the Popit.
Delicious Free Launches
With that minor setback behind you, it’s time to move onward. In the next area, a brand new method of moving through the air awaits your arrival. The nifty new pair of Layer Launchers is located there. Hop onto one and it propels you either forward or backward between layers, depending on which direction the arrow is pointed. Bounce back and forth to pop the two Prize Bubbles in the center of the screen containing the Vintage Ice Pick Object and Cracker Material.
Two more Prize Bubbles appear: one to the left in the foremost layer, and one to the right in the rearmost layer. Use the Layer Launchers to reach them and acquire the Rainbow Sticker and Red Square Sticker goodies within.
No sooner are these two popped than two more appear. Continue bouncing back and forth to pop two Prize Bubbles located in the left background and right foreground to gain the Stylized Rose Sticker and Cucumber Slice Sticker.
The Good Kind of Blues
With those wonderful new items in your Popit, it’s time to move on. Beneath a set of picnic flatware, there’s a Blue Layer Launcher. Unlike standard Layer Launchers, these only activate when you press . Use this one to leap forward to the foreground.
Reaching New Heights
Past the next Checkpoint, a bit of chicken wire drops into view. It’s time to give your sack person’s upper body a bit of a workout.
Jump off the wire from a high enough location to pop the two Prize Bubbles dangling temptingly over to the right. Doing so releases the Lemon Cupcake Sticker and Two Tone Circle Sticker.
Directly above the top of the wire wall is a single Prize Bubble to be popped for the Lady’s Hat Sticker.
Continue following Newton to encounter a pair of climbable surfaces, rising and falling side by side. Below them are two easily snatched Prize Bubbles boasting the Button Hole Decoration and Ripe Tomato Sticker.
Scale the left wire wall, and wait for it to rise higher than the one on the right. Leap to the right to pop the Prize Bubble there and gain the Flower Cupcake Sticker.
When the right wire wall reaches its apex, wait a moment before jumping back to the left and pop the Prize Bubble to obtain the Chicken Wire Material.
Leap to the next climbable surface and then off onto solid footing. Hopping up the step should automatically pop a Prize Bubble there to unleash the Butterfly Cupcake Sticker inside it.
Bouncy Bridge Boosts
Don’t shed any stuffing at the thought of crossing the tumultuous bridges ahead. Instead, regard them as a chance to jump even higher than usual! Immediately to the right of the Checkpoint, there are two Prize Bubbles dangling overhead just tantalizingly out of reach… or are they? Rock with the rhythm of the bouncing bridges to pop them!
Stand in the center of the first bridge, and just before it reaches its maximum height, hold for an extra high jump! Your sack person should have all the necessary height to reach two Prize Bubbles bearing the Bunny Ear Sticker and Biscuit Label Sticker.
This ought to allow your sack person to burst the two strings of Prize Bubbles for the Stitchem Spring Water Object, Picnic Basket Material, Flat Cap Sticker, and Working Class Leg Sticker.
Get a Grip!
Continuing onward, a Prize Bubble teeters atop a stack of three sponges. To bring it down to Earth, hold 
to grab the bottom sponge and topple the whole column. Popping the Prize Bubble now within reach awards the Green Tweed Material.
As your sack person scurries forth, two trifectas of Prize Bubbles are easily popped along the way. They provide the Saddle Shoes Costume, Bushy Mustache Costume, Round Glasses Costume, Stripy Jacket Costume, Sun Hat Costume, and Slacks Costume.
The next area features some climbable wire just out of reach. Fortunately, your sponge-grabbing skills are exactly what’s required.
First, push the smaller sponge to the right. Use it as a step to hop atop the large sponge on wheels there. From here, your sack person can easily pop a pair of Prize Bubbles overhead to receive the Frayed Jean Zip Decoration and Working Class Thigh Sticker.
Next, grab and drag the large sponge on wheels from the right and position it directly below where your sack person needs to climb. If necessary, line up the smaller sponge, as well. Then, simply hop up the sponges and start climbing!
Your sack person is clinging to oscillating wire fencing. Wait for it to reach its maximum height before leaping off to the right and popping a Prize Bubble containing Gingham Material in the process.
Slick Sliding Away
Proceeding onward to the right, drop down from the Checkpoint onto a slick slide. Play close attention to the arc of Score Bubbles above that ends in a Prize Bubble. To snag the Butter Material within it, your sack person must leap at exactly the right moment.
Once beyond the slide, use the Layer Launcher to propel your sack person into the background layer. In the process, be sure to pop the Prize Bubble holding the Open Jar of Jam Object.
As your sack person slides down, hop up to pop the Prize Bubble above to release the Blue Tit Sticker.
When you’re back to sliding, demonstrate expert timing once more to leap off at the right moment and pop a string of Score Bubbles ending in a Prize Bubble again. Popping this one nabs you the Evening Dress–Lace Material.
Pass a plate with a prominent Prize Bubble in front, and set free the Pearl Material inside it.
Swinging to the Rhythm
In order to continue onward, your sack person must swing to a higher level. Jump and grab the sponge dangling from the string. Move the left stick left and right to build up momentum. Release the sponge at just the right moment to get where you need to be!
Take a running leap through the air to ensure your sack person pops the two Prize Bubbles containing the Pink Bunting Flag Sticker and Yellow Bunting Flag Sticker there.
This plops your sack person on another slick slide. Steer carefully down the slide from right to left to pop two more Prize Bubbles and add the Butter Tray–Top Object and Butter Tray–Bottom Object to your Popit.
After you arrive at the next Checkpoint, some more simian-style swinging awaits, as two dangling sponges hang ahead. But before all that, drop down and head to the left.
Don’t fret about getting back up. As your sack person approaches the left side, a climbing surface appears to lead back to the Checkpoint and access to the sponges. Just past them is a Prize Bubble holding the Corn Stalk Sticker.
Return to the Checkpoint, and leap for the hanging sponge. Use it to swing toward the second. Release your sack person’s grip on the first, and let the momentum of the swing propel your sack person into grabbing range of the second sponge. Swing from that sponge safely onto firm footing.
A wheel-y big piece of cheese lies ahead, spinning with gusto. Your sack person can grab onto it and ride it in circles, popping a Prize Bubble in the process to nab the Cartoon Lips Sticker.
Before you get too dizzy, let go, and leap off to the right to proceed. Time the release correctly to fly through the mid-air Prize Bubble containing the Chalk Arrow Sticker.
Layer Launch Limbo
Looks like a dead end? Far from it! Drop down onto a trifecta of Score Bubbles, and your sack person is whisked onward.
The surface underfoot turns into Blue Layer Launchers. Riding down a river of jam, your sack person must bounce between these Blue Layer Launchers in the foreground layer and a similar set in the background layer. Time your launches properly to pop the series of Prize Bubbles sitting in the middle layer ahead.
Pop the first pair while launching from front to back to nab the Tartan Elbow Decoration and Curved Electric Wire Decoration. Then, pop a second pair while launching from back to front and gain the Ring Draw Handle Decoration and Sugar Cube Decoration. A solo Prize Bubble containing the Billboard Lights Sticker is next. Finally, one more pair hangs mid-air and rewards you with the Pink Long Gradient Fade Sticker and Danger Zone Sticker.
Just before plummeting to a sticky doom, your sack person is rescued by Newton’s timely intervention (and also a well-positioned goldfish bowl with its resident tagging along for the ride).
Now it’s off to Newton’s Airship to prepare for a death-defying mission!
