The show follows the adventures of a young boy named Ken, who has always dreamed of owning a car, and Bumpety Boo, a talking yellow car who hatched from an egg in the first episode, as they travel the world in search for Bumpety Boo's mother.

Teaming up seems like a natural thing, but Bumpety Boo does not count on Ken's adventurous eight-year-old spirit.

Bumpety Boo usually races them and always wins because of his strength and speed, which he receives after he smells flowers.

In 1989, Saban Entertainment had episodes of the show dubbed in English for North American audiences.

In the early 1990s, Celebrity Home Entertainment's Just For Kids Division had these English dubbed episodes released on several VHS tapes.
