Mr. Gimmick

A young girl receives a doll named Yumetarou (ゆめたろー) for a birthday present. She quickly favors the new doll over her previous five toys, who felt abandoned and unloved. While she was sleeping, they suddenly came to life and took her to another dimension. Yumetarou, as the protagonist, must track down his new owner and retrieve her from the toys' world.

The story begins during an unnamed young girl's birthday. Her father is normally busy with work, but he is able to spend time with her family for the special occasion. Earlier, he had gone to the store to purchase a new toy for his daughter.
