Supermarsu

Emilia, a suburban kid, gets a secret superpower to transform into Super Furball, who can fly and solve problems, after her pet hamster bites her finger. As Super Furball, Emilia takes on a mission to save the herring in the nearby Baltic Sea bay, which are screaming for help due to poisoned water. Character Ella Jäppinen plays Emilia in the film, which is based on Paula Noronen's children's books and features computer-generated special effects.
