S1·E34 The Sorcerer's Apprentices

A sorcerer recruits Tom and Jerry as his new apprentices. They have fun for a while, using the magic that has been given to them. But the fun stops when a past apprentice of the sorcerer comes back, and is jealous that the sorcerer replaced him. He uses his old magic to try and get rid of his replacements, while Tom and Jerry try to fight back. Since Tom and Jerry are new at this, it's not going to be easy to return the favor.
