YMMV / Extreme Ghostbusters E 23 Grundelesque

• Complete Monster: The Grundel is an evil spirit who enjoys corrupting children. The more bad actions the child commits, the more the child falls under the Grundel's influence, eventually turning into a Grundel themself. First appearing in the The Real Ghostbusters season 3 episode "The Grundel", he convinced a child named Alec to tamper with the Ghostbusters' proton packs during a school assembly, endangering all the other children present. The Grundel also manages to convince Alec to bring his brother Lee to him so he can corrupt Lee as well, despite Alec's initial protests. When Peter Venkman tries to save Alec and Lee, the Grundel tries to prevent this, stating "If I can't have them, neither can you!" He returns in this episode, taking place 10 years later. It is revealed that he has a connection to one of the new Ghostbusters, Kylie. The Grundel tried to corrupt Kylie as a child, but when she successfully resisted, he corrupted her friend Jack instead. The Grundel places Jack in a cocoon for 10 years, so that he will become another Grundel. When Kylie confronts the original Grundel about this new Grundel, the Grundel taunts Kylie about their past history and the fate of her former childhood friend. The Grundel later escapes from the containment unit and tries to corrupt Roland's brother Casey. While the Grundel knows his powers only work on children, he thinks it would be fun to murder Kylie anyway.
