Key to Rainbow Land

From WikiBrite: The Rainbow Brite WIki

When Brian puts the key in the lock of his bedroom closet, and opens it, a bright rainbow appears and takes Brian through his reality, and to Rainbow Land.The Key to Rainbow Land was introduced in the second episode of the television show. "The Mighty Monstromurk Menace (part one)" Rainbow Brite gives the Key to Brian, and says all he needs to do is put it in any door and it will take him to Rainbow Land. This key appears to be solid brass with a Rainbow and Star handle.

In the movie "Rainbow Brite and the Star Stealer", the key loses it's power as the gloom consumes Earth from the lack of light from Spectra. The key changed shape with a colored Rainbow and star handle. The Rainbow is the same colors as the Rainbow Brite's belt, with a purple star.

The key is seen again in the Feeln episode Cloudy with a Chance of Gloom. The key is found by Brian which magically takes him to Rainbow Land. The appearance of the key changed again with a full color rainbow handle with a purple star.
