Giga Watery Blowhog

The Giga Watery Blowhog is a land-based blowhog of epic proportions. It constantly births Newborn Blowlets, onto which the creature sprays radiation to allow them to spew water from their trunks. This radiation is deadly to both leaders and Pikmin alike. Even after death, the Giga Watery Blowhog continues to birth Newborn Blowlets, making Blue Pikmin the optimal Pikmin to carry its body because of their immunity to water. The Giga Watery Blowhog, beyond its new abilities, is nothing more than an oversized Watery Blowhog and as such it can be defeated as if it were one.

In Pikmin: Connection of the Worlds
The Giga Watery Blowhog is the same except for one difference; it can't give birth to Newborn Blowlets after it is defeated.
