Keys are gold with a green gem placed on them that looks like an eye. They have on top two triangle pieces that appear to look like ears. They are always trapped in a white bubble, and the top of the key highly resembles Rockitty's head.
Keys are seen floating around in bubbles and two are always present. Keys must be knocked into another to open a door. Sometimes keys can't be hit by Rockitty and must be hit by other objects. They are sometimes hidden or trapped in teleporters.
