Donny

Donny is a Micro-Dolphin living in a pool of Koopa-Kola inside Yoshi's stomach, as seen in the Nintendo Adventure Books adventure, "Unjust Desserts". He was the first of the Micro-Dolphin community that Mario befriended while he was shrunken and inside Yoshi's belly. He was amused when Mario said that the dolphins lived inside of a dinosaur named Yoshi, with whom he was unfamiliar. However, he and the other Micro-Dolphins helped Mario cross the Koopa Kola lake.
