Water Dumple

The water dumple is an aquatic grub-dog that looks like a shellfish with a big mouth. Even though it is a relative of the bulborb it doesn't have the snail-like eyes or any feet. It can eat two pikmin at a time and eats them almost as fast as bulborb larvae so you have to kill them quickly. The best way to attack is to swarm them with at least 20 pikmin or just pelt them with purple pikmin. They are found in water and on land and some times hunt in packs.Water dumples also make barking noises. I don't know anything about this, but I don't think that water dumples have reached their full size yet and they might need to advance a bit while they turn into adults. (This is just a thought for pikmin 3)

Fiery Bulblax

The fiery bulblax is a fairly rare grub-dog that is found only in pikmin 2. One is in the valley of repose, one in the perplexing pool, one in sublevel 1 of the submerged castle, three in sublevel 2 of the cavern of chaos, one in sublevel 9 of the hole of hereos, and one in sublevel 5 of the dream den. They are big grub-dogs and are slightly more aggressive than other bulborbs. One eye is smaller that the other and the mouth is in a zig-zag shape. Fiery bulblaxes have pores on their skin that produce flammable chemicals that ignite when they make contact with oxygen. This make the bulblax look like it's on fire. It will keep burning when you petrify too, but if you lead it into water then the water will extinguish the flames and you can attack it with blues. The best way to attack it is to swarm it with reds. If you are low on reds though, just pound it with purples. This will deal damage and stun the bulblax but be sure to save the purples before they die or they will burn to death.
