What are the two wooden crates for?

Push them to the monster's left side and stack them vertically to block its line of sight so the potato can pass underneath.

Where should I pass the monster?

Stay behind the crate wall and move right along the ground beneath the monster's floating platform, then enter the right-side door.

Mr Potato level guide

Stack the two central crates into a blocking wall, then rush past the monster along the ground to reach the right door.

Layout: The potato starts on the left ground. Two wooden crates sit in the center. A large monster, a floating platform, and a ground-level arched door are on the right side.
Goal: Use the crate wall to block the monster's line of sight, pass beneath the monster's area, and enter the right-side arched door.
Opening: Walk to the left side of the two crates and push them toward the monster's left side, stacking them vertically. Do not rush the monster directly.
Danger Zone: Approaching the monster head-on triggers a collision that resets to the start. If the crates are scattered, the line-of-sight block fails.
Mechanics: The wooden crates are pushable line-of-sight blockers. Stacking them vertically creates a wall that lets the potato pass beneath the monster's area.

Stack both crates into a vertical wall first, then pass beneath the monster in one move.
Do not jump onto the monster's floating platform — the exit is on the ground to the right.
Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.

Walk right from the start to the two wooden crates and stop on their left side.
Push the crates right, grouping them at the center position to the left of the monster.
Adjust the push order so one crate stacks on top of the other, forming a vertical wall.
Stay behind the crate wall, confirm the line of sight is blocked, then move right quickly past the monster's area.
Continue right along the ground — do not jump to the floating platform — and enter the arched door.
Wait for the VICTORY screen to confirm Level 42 is complete.

Approaching the monster without preparing the crate wall, triggering a collision and resetting to the start.
Pushing the crates too far, leaving the wall out of position between the potato and the monster.
Jumping onto the floating platform near the monster instead of following the ground-level exit route.
