Be careful when sliding toward the pipe in Point 1. The Dry Bones is occupying a small, cramped area and you could easily slide into it by accident. Wait for it to turn around, then slowly walk into the niche and pounce on its head.
Don’t get too far ahead on the moving platform since you don’t know if it will unexpectedly drop out from underneath you. Instead, stay near its center and watch for it to shift and turn down its predetermined path. When it does, react accordingly. For example, at Point 2, stand near the center of the platform and wait for the large icicle to drop down onto it, then leap over the icicle. If you were at the front, the icicle would crush you.
At Point 3 wait for the row of icicles to drop, then use them to hop over the spike traps in your way.
Drop a Bob-omb on the block of ice at Point 6 to create a chain reaction that demolish all the other blocks of ice. When they disappear, they reveal a moving platform underneath. Hop on and go for a ride!
When the platform reaches Point 7, jump onto the ? Block and wait for it to travel up and around. When it comes back down to you, jump to the right and hop back on!
Before going through the doors to the boss room, go down the green pipe at Point 10 to find a room with three circus balls. Bounce up to the ? Block near the exit pipe and hit it to grab a very valuable power-up, the Penguin Suit!
Boss Battle
This battle with Lemmy is not much different than the one you fought in World 3-Tower. This time, though, Lemmy rides a much bigger circus ball, which makes him even harder to reach. And to make matters worse, this time he doesn’t wait until you’ve popped him twice to fire off three circus balls! Still, your fighting strategy remains the same. Bounce from one ball to the other and get above the balancing baddie.
When you’re right above Lemmy’s head, come down on him and let him have a taste of Mario’s boot! Dodge Lemmy’s shell attack, then repeat this pounce onto his head two more times to teach this slippery slime ball a lesson.
