In Pikmin: The Final Frontier
The Feargrub is an aggressive yellow sheargrub appearing in Pikmin: The Final Frontier. Aside from its coloration and the large spike protruding from its back, it resembles a Female Sheargrub. It attacks by suddenly flipping over towards Pikmin to impale them but can become stuck in the ground by doing so, rendering it vulnerable to attack. Swarming is not a good strategy until then.
