Trevor is the companion pet version of a magical zygomite which is bought from the Farmers' Market at the Manor Farm for 10,000 beans as well as completing the Ever So Clever achievement, which requires the player to hand over a magical zygomite named Trevor with the Loyal trait, which may be obtained by trading with another player or by breeding regular zygomites as well as rerolling the name and/or trait(s) of the animal as long as the animal is male. Rerolling the name of a female magical zygomite will not result in the name Trevor, as the name is male only.
