A Gold Star

Gold Star's are the usual exits from Wonderland Secret Worlds, Wonderland Adventures and Wonderland Adventures: Mysteries of Fire Island. When you get all of the Stinkers to a gold star in a level, the level will get completed.

In Wonderland Secret Worlds, Gold Stars are usually blocked off by white gates that require a certain amount of Key Coins to get collected in order to get the white gate to open.

In Wonderland Adventures game series, gold stars are also sometimes needed to be opened by gates which will unlock other areas, but in a level you don't need to get a certain amount of coins to get to a Gold Star to finish a level.
