Dooly is a baby dinosaur kidnapped by aliens, who had experimented on him to give him a magic power. When he returned to the Earth, he got trapped in the ice glacier causing him to hibernate during the Ice Age. About 10 million years later, one of the glaciers broke off and he drifted to Seoul, Korea. He is like a typical kid who likes nothing but to eat and play all the time, but he can come across as being somewhat audacious. Behind his thoughtful words, Dooly is just another baby dinosaur who misses mother dinosaur.While in Seoul, he was found by a girl, Younghee who took him to her home with her elder brother Chulsoo. She thought Dooly was a lifeless doll, and made him live with her as pet. However, her father Kildong was annoyed by Dooly big time.He has super power that he received from aliens, but doesn't know why. He doesn't quite know how to use it but in times of danger he somehow manages to use the power.He points his right finger and yells 'Hoihoi!' He is always biting his tongue and looks silly and mischievous, but he a loyal friend. Once in a while he'll resist, like when he turns Kildong into a dinosaur and sends him to the Amazon.
