Spinning out from the upcoming WB animated feature, Super Pets: The Great Mxy-Up continues the adventures of characters fans will meet in the film! There is nothing the Super Pets love more than spending time with their heroes, but they are finding it difficult to be taken seriously as members of the team when their humans just don't understand them... When Mr. Mxyzptlk, a magical imp from the fifth dimension, arrives in Metropolis with a plan to wreak a little chaos and destruction, the Justice League is caught in his trap! The Super Pets will need to come up with a plan to prevent Mxy's mischief from destroying the city--while somehow trying to rescue their human counterparts. The only problem is, they may need to team up with their greatest enemy to succeed, and they aren't sure if they can trust her...
