In the year 1641, Shocktopus lived on the ocean floor of the India Incas. The Madballs went back to this time with the children. After Captain Weirdbeard and McCaw the Parrot defeated the Madballs, Shocktopus used his electric powers to revive the weakened Madballs and restore their strength. He then helped them defeat Weirdbeard and McCaw, leaving them at the mercy of Peg Leg Peg. Afterwards, he helps the Madballs and the children return to their proper time.
Shocktopus can give electric shocks through his tentacles. It is explained that this is because his grandfather was an electric eel.
