Martin wakes up dressed as a Viking. Today Mrs Buzzbee is taking them to the museum. There, Romeo jostles Roxanne and her ice cream winds up on the nose of a statue of the Norse god Loki. The god demands reparation for this offense and puts a pair of buffalo horns on Gromo’s head, until they bring him the eggs of the terrible Midgard snake. The kids manage to snatch the eggs, but then, full of remorse, they bring them back to the snake.
