The gum tree berries are rose-colored round fruits. Also known as "exploding berries," the gum tree berries can spontaneously explode, making them akin to small grenades. Despite that, they are known to be used as decorations on holidays wreaths.
When needing gum tree berries for her holiday wreaths, Amy set out on a dangerous trip to Hidden Meadows to pick some. This sparked a bet between Amy and Sticks, and Sonic and Knuckles over who had the best survival skills for that trip.
- Trees bearing fruit of same name have appeared in Sonic the Comic. They were found in Gum Tree Zone.
