Susshi is one of the many monsters that Dedede buys to defeat Kirby in the Kirby: Right Back at Ya! episode A Princess in Dis-Dress. When Dedede challenges Commander Vee (who at the time was really Princess Rona) to a duel, he buys Susshi fearing that he would have no chance against Vee. As it turns out, he was right. As soon as Vee pulls her blade on him he runs back giving Vee an early victory. As the crowd is busy laughing at him, Dedede introduces the "main event". The crowd goes silent as Susshi crashes into the arena and starts attacking Vee. Susshi certainly isn't the most optimal monster, as he really has no way of attacking besides body slamming. Kirby intervenes as Susshi pounds away at Vee. Kirby begins to inhale but Susshi just jumps out of the way. Dedede laughs at Kirby's feeble attempt to fight back, but Escargoon points out that Kirby was really trying to get the sword laying in the middle of the arena. Kirby inhales the sword and gets the Sword ability. Kirby tries to chop Susshi to pieces, but the sword just bounces off his thick body. Vee and Kirby discover Susshi's weak spot- his long tail. The two slice Susshi's tail into chunks and the rest of Susshi crashes back down on the arena floor. Susshi is never really destroyed per se, but he is significantly weakened having lost his tail.
Susshi is a monstrous fish creature. He has a round, tough body with burgundy scales. He has a light purple belly and white scales running across his eel-like tail and on his body. He has a dark red fin running across his back and light green fins. While Susshi's body is tough and muscular, his tail is actually rather soft and rubbery, as seen when Kirby and Vee cut it up.
- In the English dub, Susshi's name was never said in the episode, but it was revealed in The Kirby Quiz.

- Susshi's name comes from the Japanese food sushi.
