The new show from the creator of The Powerpuff Girls is a smash hit! "An admirable tale of loyalty and adventure-based learning with a contagious sense of fun." -The New York Times

Imaginary friends are forever -- that's supposed to be good news, right? Well, it is unless you have an overactive imagination like Goo. She's made up so many new friends that Mr. Herriman and Frankie won't let her come to Foster's anymore.

Then Goo meets Mac and decides that he's her new best bud. Now Mac doesn't know what to do. He likes Goo, but she keeps getting him into trouble with the rest of the gang. Can Mac get everyone to just get along?

8x8 #1 is an original story based on the hit show.
