While on a date with Carmelita, Arthur is kidnapped by the Deertown Aztecs. The Tick teams up with Carmelita to find and rescue Arthur and, in the process, gets a pet capybara named Speak.

Mr. Mental steals a device from Dr. Pendecker that lets him hypnotize Arthur and the Tick into thinking he's a baby so they'll protect him. Unfortunately, Mental leaves the device in the taxi and has to recover it.
