Mr. Gimmick 1992

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. Yumetaro had been wandering the toy store and became confused when her father came in. He hid with stuffed toys that looked like him, but was picked up by the girl's father. When the girl opens the Yumetaro gift, she is delighted. Yumetaro becomes the girl's favorite, and so her other toys no longer feel loved. One night, the toys come alive and take the girl to another dimension. The only one left is Yumetaro, who follows the toys in search of her.
