The Amazing World of Gumball - Season 3

Mom has forced Dad to install a password on the computer. The pop-up clue advises them that the password is the name of Dad's favorite child. After trying "Gumball" and "Darwin" unsuccessfully, they discover the answer is, in fact, "Anais". They are determined to become Dad's favourites by any means necessary, even if it means undermining each other, plotting against Anais or driving a wedge between mom and dad.
