Turbine Shapes Puzzle (Gel Cleaning Station)

The Turbine Shapes puzzle is located in the Gel Cleaning Station area within the Engineering Wing of Chapter 5. When you enter, you immediately see a large wind turbine and a screen displaying three large red shapes — but these shapes are randomized for every player, so copying another player's solution will not work. To solve the puzzle, note the three shapes on the screen from left to right, then use your Blacklight to find the corresponding shape symbols near the various switches around the turbine. Pull the three matching switches in order and you will hear a confirmation ping when correct. This turns off the generator and allows the turbine blades to stop, letting you pass through the tunnel. After solving, do NOT leave immediately — there is a highly missable secret room beneath the staircase you entered from. To access it, smash through the Poppy Gel goo in the corner of the room using Pressure Hand. Inside the secret room, use the magnetic ceiling strip to reach the upper level, push a storage box down to the lower level to jump over pipes, then hit the green switch and immediately pull the lever before the liquid passes the red line. Sprint through the door and drop down to find the Golden Chum collectible (Chum Chompkins gold figurine, collectible 6 of 19). This is one of the most commonly missed collectibles in Chapter 5.
