Sidekicks Don't Kiss (S03E03)

The Deerfield Aztecs, a baseball team, find themselves stranded in Mexico, where they unintentionally establish their own tribe of Aztecs. They embark on a quest to find their missing shortstop, Carmalita (Arthur's girlfriend), but mistakenly capture Arthur instead. As The Tick and Carmalita chase after them, the Aztecs, led by Wally, unleash a creature named "Speak," whom they plan to marry off to Arthur. The Tick grows fond of "Speak" and ultimately defeats the Aztecs, freeing Arthur from their clutches.
