Grubby

Grubby is one of three critters that occasionally spawn in the Jungle or Underground Jungle biome when a player breaks a background plant (using any pickaxe or drill), the others being Sluggy (rarer) and Buggy (rarest). Grubby is the most common of the three. It can be caught with any type of Bug Net, and used as bait with Bait Power.
