Tuber (Trainer class)
A Tuber (Japanese: うきわボーイ Ukiwa Boy and うきわガール Ukiwa Girl) is a type of Pokémon trainer that first debuted in the Generation III games. They are very young children in inner tubes. They come in male and female versions.
They generally use a combination of Water-type and Normal-type Pokémon - particularly Marill and its related forms..
