The Goblin Squad are four, devious and mischievous goblins who form and pull pranks in their treehouse hideout. The Goblin squads consist of Wally(the leader), Rick(The one with the skull mask), Hicky( The one who loves animals), and Betty(the token Female goblin in the group).
All they do is pull pranks on Mike and everyone. Nothing more, nothing less. The pranks can be pretty creative too. Despite them being goblins, they are considered "children" by goblin years.
