How do you open flopsides pit of 100 trials?

Answer 1

First! To be able to unlocked flopside pit of 100 trials, you have to complete flipside pit of 100 trials, If you do not have luigi after you complete flipside pit of 100 trials, go to flopside outskirt B2, and used tippi's power to reaveal hidden blocks, that would lead to a large platform flip to 3d and pass through the allow gram wall, this will lead you to flopside B2 directly above the pit of 100 trials. Used fleep to open the crack and then hit the blue switch, If you have luigi simply go down to the first floor of flopside than use the down elevator to go flopside B1 then found another down elevator to go down flopside B2, then used luigi super jump to reach the top of the wall, then used fleep to open the crack.
