Martin discovers an excavation in his garden: he's an archeologist, an Egyptologist! Accompanied by his faithful friends, he discovers an underground tunnel leading straight to a real pyramid..has he found the lost treasure of Pharaoh Tutmancomon?

Nine-year-old Martin wakes up each morning as a different type of being, and though it isn't always easy for him, his friends accept him and join him on adventures inspired by each transformation.

On this cold winter day, Martin wakes up as a werewolf! It's not much fun being scary: at school, he terrifies Mrs. Buzzbee, causing an incident that requires him to go and clean up in the restrooms.

Waking up, Martin discovers he is a warden at the city animal park. He is about to go out, when on TV, a news flash announces that the park's fence has collapsed, and "dangerous" animals have escaped.

Martin wakes up dressed as a Viking. Today Mrs. Buzzbee is taking them to the museum. At the museum Romeo jostles Roxanne, and her ice cream winds up on the nose of a statue of the Norse god Loki… who is not pleased.

Martin wakes up wearing a full basketball kit. Gromo is impressed by his appearance, but Martin tells him, it's just the kit, he doesn't know how to play.
