Introduction[edit | edit source]
You can only do this in a select level in Infinite Mode.
Gameplay[edit | edit source]
The Bunny is good because of its hopping, letting it able to crumble the tiles on the wall without changing gravity.
Another good choice is the Duplicator, as you can just get your clones to break the crumbling tiles with their heads. That way, you don't have to risk falling into the void when you go back. However, be careful to not rotate the tunnel with your clones.
The Student also does well because you can activate the Student's ability right after you bump your head on the crumbling tile, giving you more time to move back into the tunnel before you fall out.
This is risky but you can break it from the outside with any character(except the Child and Pastafarian, to see why, go to A Breath of Fresh Nothing), go outside the tunnel hit your self on the crumbling tile and you will float up, if you hold the side button(whatever side your on like if you are doing on the left, hold right, and you get the idea) you will go back into the tunnel and you can do this again.
