Gold Star
Gold Stars are the usual level exits in Wonderland Secret Worlds, Wonderland Adventures and Mysteries of Fire Island. When you get all Stinkers to the Gold Star, the level is completed.

In Wonderland Secret Worlds, Gold Stars are usually blocked off by white gates that require a certain amount of Rainbow Coins to be collected in order to open.
In Wonderland Adventures gold stars are also needed to open gates which unlock new areas, but in a level, you don't need to get a certain amount of Rainbow Coins to get to the Gold Star.
