Toxic Dumple

The Toxic Dumple is another type of aquatic grub-dog that behaves similarly to the Water Dumple. In PSI, Water Dumples behave as they did in the first Pikmin game, meaning they are fast enemies. Toxic Dumples on the other hand, are slower. With every inch they move, they excrete a short-lasting cloud of poison gas (similarly to the Doodlebug) as they advance towards their prey. Because they are usually found in water, the gas they emit will be a problem for your blues if they want to defeat this enemy. Creatures like these are sometimes better off being punched by captains instead.
