The InterChet is a large cube who runs the Flipside Arcade in The Flip Flop Show. He offers a variety of games that Bleu and his party can play to win various prizes. He also runs the rewards center, the same way Lahla did in Paper Mario: The Thousand-Year Door. Although his Catch Card reveals that he is the inventor of the similar character The InterNed, both Muffy and Sipsi state that almost nothing is known about the InterChet; he's "literally a black box". Judging form some quotes, It can be said that the InterChet is a con artist. The InterChet's name is a portmanteau of "internet" and the name "Chet".
