Pamela was a mooshroom cow adopted by Rendog. In his Season 7: Episode 1, Rendog killed all the cows on the mooshroom island except Pamela and decided to keep her. Then he sat in a boat with her, but there were all sorts of bad weather and Ren and Pamela shipwrecked. Pamela arrived on Loser Island with Rendog. She died in an accident with The Boomers.
Pamela was kidnapped by iJevin, who called himself 'The Beef Thief'.
Rendog has since joined the Mycelium Resistance to bring justice to Pamela's homeland by reintroducing mycelium back to the island.
