Its main method of attack is to throw up a gloom projectile, which creates a ring of gloom when it lands that slowly expands until it dissipates.

In Pikmin 4, the egg takes a varying time to hatch, depending on the location. Once defeated, it explodes and leaves behind a pearl. By merely moving towards them, it can kill them or damage Olimar simply by having the gloom come into contact with its target. After this, it will begin chasing after Olimar and the Pikmin. Once it is there, it will perform a gesture that uproots any Pikmin sprouts, even if there are none. Its first goal is to go to the landing site, ignoring any prey.

The beast itself is a dark green creature with glowing eyes. If the egg is destroyed before that, the beast is killed, though in Pikmin no reward will be produced. The creature is initially found inside an egg, and will break out after some time. In Pikmin 4, its egg can be first encountered in a night expedition, specifically the Feasting Center in the Hero's Hideaway. In Pikmin, it is an optional boss fight, and the only way to encounter it is to visit its egg in The Distant Spring on or before the fifteenth day. The Smoky Progg ( ドドロ ?) is a boss found in Pikmin and Pikmin 4 and is considered one of the hardest encounters in the series.
