PunkBob SpikePants is the evolved form of SpongeBob in the movie Lock Evolution: Evolved, and in the show Lock Evolution Z. In the movie, SpongeBob mainly uses it as well as the Snails in order to try and take down Pearl's Lock to Live, and later, to defeat Leader and his popstar minions. PunkBob was good-natured (like in his original self, SpongeBob) but also develops a skill on mastering the rock guitar better than anyone in the world! He is voiced by Chris Pratt.
