Corazon lies about having a famous uncle - Dude from "The Descendants" - not knowing the real Dude is coming to Pup Academy to judge the annual talent show, as Morgan and Charlie engage in the ultimate prank war.

Corazon gets himself into big trouble when his mischievous neighbor, teacup pup Oopsie, named after the only word she knows, follows him through the secret fire hydrant portal to Pup Academy where 'no outside dogs are allowed.' Meanwhile, Morgan tries to tech-up the school with not-so productive results.

After a bad day at Pup Academy, which makes Spark question where she belongs, Spark is ready to quit the Academy for good. But when she skips school to hang with King and the Lost Dogs, Spark learns the grass isn't always greener on the other side.
