He attacked Randy and was about to kill him when Howard tossed a cindar block at him knocking him down. Catfish recovered and tired again to kill Randy. But Randy managed to break free and distroy his magic powder leaving him powerless. Now like this his animals turned on him and chased him off.

In "Welcome Back Catfish" its revealed that due to having The Sorcerer's Chaos Pearls, it means the Sorcerer can now control Booray remotely, doing this he has him enlist as a Teacher at Norrisville High to find the Ninja. Then later the Sorcerer forced Booray to swallow the Pearl, transforming him into a monster. Heading towards the Tengu stone, the Sorcerer channeled even more magic into him making him more powerful. Randy arrived and faced him, however he couldn't change him back, thankfully Howard overheard the Sorcerers plans, and revealed he needed to be near the Tengu stone for the Sorcerer to remain in control.
