The Amazing World of Gumball (2011)

S5E26 The Sorcerer

Gumball can’t bear the thought of being the only kid at school without any special abilities. In his determination, he persuades Mrs. Jötunheim, Hector's mother, to mentor him as her apprentice. However, it doesn’t take long for her to realize that allowing Gumball to experiment with magic on his own is a huge error.
