The plot you mentioned might have come from the cartoon One Piece. In this cartoon, there was a character called "Monchi D. Luffy". He was an adventurer who sailed with his companions on the sea in search of legendary treasures. During their journey, they had once visited an isolated island and met a character called " Dumbo."
Dumbo was a character with a unique personality. He looked a little silly but was actually very smart and like his companions, he was moving forward to realize his dreams. In this plot, Dumbo was persuaded by Luffy and the others to join their adventure and spend an unforgettable time on the island with them.
