Ladder Needs a Wash is the 41st level in Chip's Challenge Level Pack 2. The level is indeed shaped like a ladder, with chips on the rungs, and a little bit of dirt. However, the job is complicated, in Drew Thomas fashion, by some teeth. Even step is required. Continue with rung 8, but the teeth are too close to step directly back onto the base column; move down one row further and L 3D LU 6L DL. Now, Chip can take the rest of the chips similarly to the top egde of the ladder and move to the exit in the southeast (hinted at in the level hint at the beginning).
