The world is a scary place, but what can be more fun than making your world a scary place just the way you like it? Talk about feeling in control!
When you start this level, your sack person immediately finds a Prize Bubble containing the Squashed Sackthing Sign Sticker. Head up the lift, and jump to pop the Prize Bubble for the Dangerous Sticker.
Set fire to the blocks to turn the Sackbots into little infernos, which are recycled.
Proceed down the platforms, jumping to collect the Prize Bubbles for the Small Scissors Sticker and Yellow Radial Fade Outwards Sticker.
Unlethalize the platform and rotating sponges to proceed through the next area. Press 
to pause the action if things are moving too rapidly for you at first. Don’t miss that hidden Prize Bubble in the middle of the rotating sponges. It’s tricky to hit, but it’s definitely worth it for the Warning Stripes Material.
Once you unlethalize the next platform, you can climb to the level above and collect the Prize Bubble there for the Chalk Sackboy Arm Sticker.
Immunities
Sackbots are immune to whichever elements they’re already affected by, so if you see a fiery Sackbot, you can bet it’s immune to Fire. In the next room, help the Sackbots reach their destinations by turning the orange blocks hazardous for them, keeping their immunities in mind. Your sack person gets some Prize Bubbles in return, snagging the Chalk Sackboy Leg Sticker and Curved Chalk Line Sticker.
Use the sponges to swing up and jump onto the next high platform. Make sure your sack person pops the Skull ‘n’ Crossbones Sticker and Grill Vent Cover Decoration along the way.
See the block up ahead with a Sackbot on top of it? Select Horrible Gas from your Tools bag, and apply it to the block to turn it into gas. The Sackbot is sucked in and vaporized in the process, but it’s okay: it’s only an automaton with no real thoughts or feelings.
Do the same with the next platform to unleash the Prize Bubbles for a Mutant Fish Decoration and Atom Symbol Sticker. Next, your sack person can take a big leap to collect the Goat Body Sticker and Goat Head Sticker.
Apply Horrible Gas to the platform at the top of the screen to allow the sponge to pass through it. Now, you can unlethalize the platform up ahead, and then push the sponge using 
so your sack person can reach it.
Select your Unlethalize Tool again to apply it to the electric sponges you see up ahead. Once they’re safe to touch, your sack person can use them to swing upward to the next platform.
Unlethalize the platforms with the Unlethalize Tool to stop the spikey blocks from falling and blocking your sack person’s path.
Pass through the next Popit Powerup. Move to the far left where a sole Prize Bubble is tucked behind an orange barrier. Let it loose by turning the obstruction into something less substantial by using the Horrible Gas Tool. That drops the Prize Bubble right into your sack person’s lap for the Pop Rivet Decoration.
Use the Bounce Pad to launch your sack person up to the platform above, pop the Prize Bubble for the Neon Horse Sticker, and then jump to grab the Sackthing Lift Sign Sticker.
Don’t forget about the Prize Bubble on the far left. Apply Horrible Gas to the orange material there to let the Prize Bubble holding the Pop Rivet Decoration drop.
Unlethalize the sponges, and use them to swing your sack person up to the next platform.
The next part is a little trickier. Use the Horrible Gas Tool on the orange materials to let the spiked blocks and Prize Bubbles lower. Don’t forget about the orange block at the bottom right. Next, use the Unlethalize Tool on the orange materials to block the gas from reaching your sack person as they make their way over the obstacles, collecting the Parcel Tape 2 Decoration and the Rubber Glove Decoration from the Prize Bubbles there.
Now, take the lift to the exit.
