The Superpet Superhero League has finally figured out how to reach the water fountain all the students use. This is so much easier than battling Whiskerface and his Rat Pack every time they go to the cafeteria to quench their thirst! But as soon as the last superpet has taken their turn at the drinking fountain, they all realize they have a big problem. The water won’t stop flowing. Is this actually a terrifying Fountain of Doom?! How will the superpets stop the fountain from flooding the school? And which of the pets can even swim?!
