372 route: Play in even step. Barge through the block columns using wedges (going down, then up, then down), collect both red keys, open the top door, move to R of it, then return and go down to the bottom red door (this will lure the teeth away from the bottom door for long enough to sneak past). Go round the bottom of the first wall column, then past the third teeth monster to the top right corner of this room. Wait for the teeth to reach this row, and lure it into the top middle bomb (this can be done by waiting L U from the socket after luring the teeth onto the top row). Go round the bottom of the bombs, wait underneath the leftmost one as the other 2 teeth enter the room, then move right and up just as the lower teeth moves onto the bottom row. This should cause the 2 bombs in the lower-left to be exploded. Collect all the chips then teleport. Use the green buttons to lure the bug into the next room, then use the blue buttons to lure the bug onto the trap button. Go through the trap. Now use the blocks to build across the water. It appears as though Chip is 1 block short – however he can return to the start (pressing the blue button on the way for the fastest route) and build down from the start room to the room below, and take a block into the exit room. Note that pushing a block into (27,22) may make the route quicker.
