Master Udon

Master Udon

Master Udon is the main antagonist of the episode Karate Island. Udon is the fish that calls SpongeBob to come to the mysterious Karate Island. He is actually a con man because he captures SpongeBob and tries to make him buy real estate. He has quite a few recruits and orders them to stop Sandy from getting to him, though they are unsuccessful. Sandy then confronts Udon himself, and he is revealed to have extremely large muscles. Despite this, Udon loses a karate fight to Sandy and falls from his condo, landing in the water and possibly dying until he returns at the very end of the episode (as a pun joke). He is voiced by actor Pat Morita.

Trivia

• At the end of the episode, Udon is back to normal after falling from a high distance and greeting Squidward to become "King of Clarinets".
• Near the end of the episode, Sandy says "You're in the soup now, Udon!" Udon is actually named after a type of noodle soup served in Japan.
• He presumably works on the 4th floor of the "four floors of fear".
• Udon is the last role Pat Morita had of any significance; he died just after he finished the episode. The episode is dedicated in his memory. Aside from an appearance in Ma and Pa's Big Hurrah, Udon has not appeared again since "Karate Island," likely in part due to Morita's death.
