Superhero Training Academy

The Superhero Training Academy was a day camp that was advertised to "Unlock your child's inner superpowers!". Greg and Rowley wanted to do it so they could overpower Leon Feast and his friends, but they realized it was a scam. They were stuck there for a week and had to participate in childish activities like the wall smash station (Which WAS a wall smash station, but it was just rubber bricks stacked onto each other.) And at the end of the week, Greg and Rowley only received some lame certificates saying Greg was a superhero for showing good manners during snack time. Rowley's certificate's contents are currently unknown.

Trivia

 * Since Greg's certificate mentioned "snack time", it can be assumed that the program was targeted towards young children Manny's age, and also because they wouldn't know that it was a scam.
