Bingo is the leader, front man, drummer and possible founder of the Sixties pop group known as The Mosquitoes. As the leader of the group, he does most of the talking and planning for the group, and when they meet the Castaways, he promises to take them off the island after a month. He's identified by his long hair, blue shirt with polka dots, animal vest and red pants. He also wears a long nightshirt to sleep. He refers to the Skipper as "Commodore." However, he doesn't stay the full month on the island and doesn't live up to his promise to rescue the castaways.
- Bingo was played by actor Les Brown Jr..
