Instructions
Pagoda
Use "Paint" to restore the bridge to the pagoda. Cross the bridge.
Use "Paint" or "Thinner" on the Splatters on the pagoda platform, then walk around to the back of the pagoda.
Use Mickey's spin attack to turn the gear on the back of the pagoda, then climb to the second floor.
Walk around to the front of the pagoda and free the gremlin from the cage. This will cause the boats to circle the pagoda area. Jump onto any boat and proceed to the purple island. Free the second gremlin.
Fan Blades
Jump onto one of the boats and proceed to the series of rotating fans at the extreme right.
Use "Thinner" on the blue blades for each fan to make an opening, then jump through each one.
Spin the dial at the end of the fan tunnel to turn off the steam, then proceed quickly back the way you came. Turn off the other three dials as you pass.
Look up when you reach the first fan. A treasure chest is inside an opening in the ceiling. Jump up and grab the treasure chest. The pin inside will appear in your collection.
Take a boat back to the purple island and then use "Paint" to restore the bridge made from playing cards. Cross the bridge.
Use "Thinner" to dissolve the red wall, then run to the end of the corridor.
Gears
Jump on any boat. Ride the boat to the area with the gears.
Use "Paint" to stop the gears, then climb the platforms to the top.
Use "Paint" to hit the yellow switch, then cross the dragon-shaped bridge. At the tail end of the bridge, jump onto the cloud. Ride the cloud to the blue platforms, then jump onto each of the blue platforms in turn to open to exit door.
Go back to the entrance to Asian world. Dissolve the gear to free the third and final gremlin. Hop onto a magic carpet and sail out of Asian world.
