223 route: Play in odd step. Pick up the flippers, enter the top left room, and wait  before pushing the block onto the brown button. Collect the 9 chips and fire boots, then leave via the fire (the teeth will burn). Go down to the bottom left room, wait , remove the two blue walls immediately underneath the upper trap, then remove the middle row (excluding the outer walls), then the wall to the left of the lower trap button. Move immediately down and collect the chips behind the lower trap, then the upper trap (you should only have to wait ). Collect the chips in the bottom middle room, then the bottom right room (enter via the top and collect the chips clockwise, finishing with the leftmost chip). Now teleport LR and stand UL from the teleport. Move R just as the second teeth enters the teleport (from the right), collect the chips in this room, then teleport L into the middle left room. Push the nearest block LUL, wait  and collect the chips from the bottom right (3 paramecia will be left circling thin air, the rest will drown). Teleport R and move to the top right room. Remove the dirt, collect the first 2 chips, backtrack to let the bugs out, then collect the last chip. Finally, enter the top middle room, collect the chips at the top, then the chip by the skates, and slide down to the exit.
