Superhero Training Academy

The poster

The Superhero Training Academy is a day camp at the YMCA that appears in Diary of a Wimpy Kid: Hard Luck. It is advertised to "Unlock your child's inner superpowers!"

Greg and Rowley enroll so they can gain powers to defeat Leon Feast and his friends. However, they realize that it is meant for kids younger than them and does not give them real superpowers. One activity is the Wall Smash Station, in which the attendees run through soft, fake bricks. When the camp ends, Greg gets a certificate deeming him "a superhero at showing good manners during snack time."
