Purple Bulborb

This variation of the Red Bulborb actually sleeps for 10 seconds after you begin attacking it.

Purple Bulborbs in PSI
These bulborbs are about the size of one on Pikmin 2's small Emperor Bulblaxes. They are actually female Red Bulborbs. They're heavy sleepers, so you can beat up on them from behind for a good couple of seconds before they start to retaliate. The problem is, once they've been woken up they won't go back to sleep. They'll just stand up on their legs and look around to make sure there's not a threat nearby. With their large mouths they can swallow many Pikmin at once, and after they take more than 50% of damage they'll begin to roar, which calls Bulborb Larva out of the ground to attack. This powerful creature could almost be considered a boss itself, but rather like certain powerful enemies in the first Pikmin games, it is more of a mini-boss. Portal- Kombat

In Pikmin: Ultimate Doom
The Purple Bulborb is much different from it's former appearance. In Pikmin: Ultimate Doom it is awake at all times. It trudges around and eats any trespassers.

In Pikmin: Rise of the Plantae
The Purple Bulborb is purple with yellow spots. If it is awakened it will not go back to sleep until the end of the day. The purple bulborb has the same health as a bulbear and like the bulbear has no limit on where it will chase you. It can go anywhere on the map once awakened and you must go very far away from it before it stops chasing you. Try to kill it with Purple Pikmin or bum rush it with a huge number of Pikmin.
