Gameplay
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 wake up and have to replay the level, or sometimes restart the entire game.
Barbie can also request help from animals by selecting (pressing SELECT) one of the charms on her charm bracelet to signal what sort of thing the animal should do. Pressing the B-button then to throws the command. If the command reaches the animal, the animal will do the command requested.
Sometimes Bosses will appear, these challenges are usually overcome with the help of an animal.
