After Mac yelled at Goo when he was told that he won’t come to Foster’s anymore, he’s decided to leave, never to return. Everyone at Foster’s no longer cares for him. Not even Frankie, his now former girlfriend. The only one who cares about him was Goo, Yogi Bear, Boo-Boo, Quick Draw McGraw, Snagglepuss, Huckleberry Hound, Augie Doggie, Doggie Daddy, Top Cat and his gang (Benny the Ball, Brain, Chow-Chow, Spook, and Fancy), Snooper, Blabber, Magilla Gorilla, Wally Gator, Peter Potamus, Squiddly Diddly, Mr. Jinks, Pixie, Dixie, Baba Looey, Atom Ant, Cindy Bear, Hokey Wolf and Touche Turtle.
