Mac Tonight was Happycat's closest ally. He was a guy with a moon for a head. He started out as a guy on the street, but Happycat randomly chose him to bless with the power of nigh-invincibility. He eventually became Happycat's advisor and fought with him against Bonzi Buddy and Geoffrey the Evil Toys-Backwards-R-Us Giraffe. Unfortunately, Mac was hit with a Bonzi Brainwash Bomb during the McDonaldland Shootout and was brainwashed to join the Bonzi Army. Shortly after he joined the Bonzi Army, he was killed when Billy Mays suffocated him with Mighty Tape. Happycat appointed Billy Mays as his new advisor, a position he still holds today.
