Buck is a main character of Oscar's Oasis. He is a vulture, and the nerd of the trio.
He always approves when Popy yells at Harchi.
- The reason why Buck doesn't fly is probably because he is old to fly or probably it's because of his weight, but in some episodes he does fly.
- Buck appears as an NPC in ToonWorld All-Stars Online, alongside Popy and Harchi.
