Barbie is an English language video game for the Nintendo Entertainment System by Hi Tech Expressions starring Mattel Inc.'s Barbie. It is one of the few explicitly girl oriented Nintendo Entertainment System games.
Unlike other Barbie games, Barbie is designed as a platformer. Barbie's levels are "dreams" and each "dream" has Barbie walking left to right while avoiding obstacles or else her "Zs" will drop and she will have to replay the level, or sometimes restart the entire game.
Barbie can also request help from animals by pressing SELECT to choose what sort of thing the animal should do and B to throw the command, if the command reaches the animal, the animal will do the command requested.
Sometimes "Bosses" will appear, these "Bosses" are usually defeatable with the help of an animal.
