Mr. Chupon is a boss enemy in the Super Nintendo/Super Famicom game Final Fantasy 3 (US)/ Final Fantasy 6 (Japan). He is a large purple monster, whose only words consist of "Fungahh!"

Mr. Chupon appears relatively early in the game, and is summoned by everyone's favorite evil octopus, Ultros. After Ultros summons him, you will have to inflict around 10,000 hit points of damage on Chupon, and then he will use his "sneeze" attack and blow you off to the next battle. To the best of my knowledge, you can't defeat him in this boss encounter.

The other place you may encounter Mr. Chupon in this game is in the Colosseum, where he is pitted against you when you wager items easily available in the shops of the game world.

Remember, as Ultros says: "He's taciturn, but terribly powerful."
