- Suika Hime

Suika Hime (スイカ姫, Princess Watermelon) is a character that appears in the last chapter of Super Mario-kun volume 1 as the princess to rescue in Super Mario Bros. 5, the hypothetical sequel Mario, Luigi, and Yoshi end up in.

After defeating Bowser, the heroes and their guide, Isshī, reach the princess in her chambers, but only then Mario realizes the "princess" Isshī was talking about wasn't Princess Peach, but Suika, a princess that, in line with the Super Mario Bros. 5's world inhabitants, has a weird face, having a big watermelon as a head on a human body.
