The Submarine

Nolik, Fire and Toola are watching a movie about a submarine adventure and decide to build one for themselves they can sail inside the aquarium. They collect parts of old toys, build a submarine, put it in the aquarium and get in. But very quickly algae wraps around its propeller and the Fixies find themselves trapped. They start running out of oxygen as scary fish with huge teeth smash against the window! What can the Fixies do?! Toola is scared more than everybody, but suddenly she has an idea: if they switch around the electrical contacts in the engine, the propeller will start turning in the opposite direction. Hurrah! The idea works and the algae unwinds. The Fixies safely get out of the aquarium and decide that the next time they should build a helicopter!
