Dwarf Mutated Bulborb

The Dwarf Mutated Bulborb is simply a Dwarf Bulborb, but mutated by harsh radiation. They look exactly like a Mutated Bulborb only smaller. These incredibly weak creatures are only half as strong as a Dwarf Red Bulborb, and can only eat one Pikmin at a time. Although weak, they will spew out incredible radiation when killed, killing any Pikmin nearby and drawing Grey Pikmin towards them. They will also leave a pool of acid, water, lava, poison water, or their body will explode. You must use whatever type of Pikmin needed to collect the body.

Strategy
There really isn't a strategy to kill these except to run after you attack.
