Speed gets chased to the edge of a cliff. The gorillas throw boulders at him and one knocks him off the cliff. General Smasher, who is watching Speed on the monitors is happy to be rid of ""that nosy young man"" once and for all. Smasher resembles Hitler, another fun-loving character from the 1940s. In order to secure Professor Carnivoré's cooperation, Smasher leads him into a room where he meets a former colleague, Professor Loon. Professor Loon shows off a giant gorilla. The gorilla often bites through the chains and escapes. Loon is summoned to the command post because the Mach Five is approaching the island. As the Mach Five approaches the island, a door opens underwater and the car is sucked inside. As Trixie and Spritle reach the end of a long tunnel, tanks are waiting for them.
