Spoiler warning: This walkthrough covers the route to Safe Haven in Poppy Playtime: Chapter 4, including the locked gate and gear maze. The Blue Tower locker code is 3021.
How to clear the locked gate
After meeting Doey the Doughman, follow him toward Safe Haven. At the locked gate, gather the chain hooks and four levers, then use the Blue Tower locker for the missing lever.
- Collect the chain hooks attached to the wall. Attach two hooks to each door handle.
- Fit the four levers. One is already attached to the gate; pick up the other two from the floor nearby.
- Climb to the locker atop the Blue Tower and enter 3021 to retrieve the last lever.
- Attach all four levers, then flip them with your glove to open the gate.
Find the three gears in the maze
Continue through the corridors until you reach the gear maze. The gear locations depend on which entrance you use, so note the gate named in each direction below.
- From the left gate: Look on the steel shelf to the left as you enter.
- From the center gate: Check behind the two stacks of blue boxes in the right corner.
- In the center of the maze: Find the third gear on a steel shelf.
Set the gears and reach Safe Haven
Place the largest gear in the middle position and the two medium gears at the ends. This is the last puzzle before Safe Haven. After solving it, you reach Safe Haven with Poppy and receive the next objective: find the Doctor and get the Omni-Hand.
