A Glow Berry is the glowing lure of a Depths Worm, dropped as loot upon its death. When eaten, it restores 11 and 25 but reduces by 10.
A Glow Berry will also cause any creature that consumes it, including Bunnymen, Pigs, Splumonkeys, Prime Apes and Gobblers, to glow. The intensity of the glowing light decreases over time and will extinguish 90 seconds after consumption. If dropped on the ground, it will glow, similar to a Light Bulb. It emits enough light to prevent an attack from Charlie.
In all DLCs, Glow Berries can be stacked up to 10 in the player's Inventory.
In the Reign of Giants DLC, Glow Berries can be used to craft Moggles. Additionally, they can be used to refuel Moggles, extending their durability by 33%.
