Sully, the MonSquad, and members of the Monsters Power Players participated in "Boo at the Zoo" at the Cleveland Zoo over the weekend. The Power Players painted faces and gave tattoos away while Sully and the MonSquad could be found dancing in the "Monster Mash" dance tent with lucky fans. The Monsters were located in the Wild Wings portion of the zoo, so Sully was able to hang out with his Flamingo friends.
