The Lawn Gnorme is the teritary antagonist in the Phineas and Ferb episode, Excaliferb. He is the fantasy counterpart of Norm and the assistant to the evil wizard Malifishmertz.
History
He only appears when Malfishmertz summoned him to trap Parable the Dragonpus (the fantasy counterpart of Perry the Platypus) in a wicker cage. The Gnorme would later show the Meatlings that Malifishmertz have created in order to take over the Tri-Kingdom Area. It is unknown what happened to the Gnorme afterwards during the final battle, either that he may have escaped or not.
