Miao, Guau and Tua have made up a little play that Dad is going to record on video. But the Tree character has not been assigned to anyone. Someone has to be the Tree! Tua? Guau? Miao? They each try to switch from their original character to being the Tree but none of that works because they are each needed to play their original characters. Miao thinks about it and figures out they can leave the camera recording on the tripod and DAD can be the Tree!
Every day, to transform out of his secret identity as a mild mannered suburban father, DAD dons rubber kitchen gloves, a speedo and rubber rain boots over his jeans, a tablecloth for a cape, and the pièce of résistance, a silly blue “hero” mask over his eyes… and voilà! DAD is now HERO DAD!! In every episode, DAD teaches MIAO how to solve challenging situations that every 3-year-old has to face: Do superheroes wash their hands before eating? Why wouldn’t superheroes throw trash on the ground? Are superheroes brave even if they like to sleep with a little night light?
HERO DAD guides MIAO through the everyday lessons of a 3-year-old’s life, as a superhero… albeit a clumsy superhero that’s always getting himself into trouble! He is supposed to be the hero, but he always ends up being saved by MIAO, who in turn learns the lesson of the day in the best way possible: laughing and having so much fun with her DAD!
