How to Get Gus Out of the Jungle in Epic Mickey

Play the game until you get to the "Jungle Boat Ride" stage. When you go through the door, jump across the boats in the water until you find a ledge. Walk along this ledge until you find a sweeper enemy. Use the paint or the thinner to defeat him, then use the thinner to clear the paint off the wall behind him to get into a secret passageway.

Spray paint or thinner on the hippo heads in the next room to open the door. Go through the door and fight another sweeper. Use the thinner as you did in the above step to reveal a hidden path. After you talk to the gremlin in this room, use the paint on two of the gears to lower the pillars.

Jump across the top of the lowered pillars to leave the room. Use the thinner on each painted section you come across to clear them. Cross the bridge when you come to it and free the gremlins that you come across. When you get to the third bridge, jump onto the tree branches above. Paint the platforms above and jump on top of them to get a prize, then drop down below.

Jump across the gap and fight another sweeper. Jump down into the cave below and the gremlins you saved will appear and turn the valves above. This will release a few sweepers, which can be defeated with paint or thinner. Once they are gone, run through the pathway and jump on top of the piston and jump off of it to reach the above walkway.

Jump down to the final area where you will meet Gus. Step on the plate in the center of the room to deactivate the steam. Use your spin attack on the three valves to turn them and the door will open. You will see a cutscene where Gus escapes through the door and out of the jungle.
