Red fruit

Red fruits are obstacles that appear in Shadow the Hedgehog.

Overview
Red fruits are plants that are brought to Earth by the Black Arms, where they dot the landscape, though it's not clear how they were transported to their locations. If the player touches them they will be harmed, losing either rings or their sheild if they have one. They are one of the very few, rare enviormental objects that, upon being destroyed, will fill the Hero Gauge.

They appear to have the same texture as red slime, which may hint at a connection.
