This enemy is a bulblax that has been infused with Doom Essence. It is much more aggressive than the average grub-dog, eating pikmin incredibly fast in large amounts (up to 30 at a time). The bulblax can use the Doom Essence it is encased in to enslave pikmin and turn them into Doom Pikmin. Occasionally this creature will roar in a similar manner as the Emperor Bulblax, summoning all nearby grub-dogs. When this bulblax realizes that it is about to die, it will shake off nearby pikmin and jump a short distance into the air, killing all unlucky pikmin beneath it when it lands.
