Pop is one of the main characters in Happy Tree Friends.
A light brown bear. He is an adult character. Some people refer to him as the stereotypically clueless, bathrobe-wearing, pipe-smoking 1950s style sitcom father. Pop only appeared without Cub in Something Fishy (excluding his BBQ smoochie,Milk Pong, and the end of Tunnel Vision), though Cub has appeared in multiple episodes without Pop. He was originally going to appear in Happy Trails Pt. 2: Jumping the Shark, but the creators considered it weird for Pop to hurt Flaky. Instead Flippy took his place which explains why Flippy had Pop's voice. Though Pop is likely an adult character, he is not as large as other adult characters like Lumpy and Giggles' Mom.
