Acid Dumple

The Acid Dumple is a species of grub-dog that dwells in acid or leaves a trail of it as it moves.

In Pikmin: Back in Action
Acidic Dumples appear in Pikmin: Back in Action. They act as all of the other dumples, but they live near acidic elements.

In Pikmin: Return to the Distant Planet
Acidic Dumples also appear in Pikmin: Return to the Distant Planet, and they mostly appear in or around acid pools or acid gas, making them dangerous. Acidic Dumples secrete acid, evaporating all but Green Pikmin that come in contact with it. If attacked by Green Pikmin, the dumple will shake them off, and then attempt to swarm and eat them. A simple strategy is to quickly throw Green Pikmin onto the dumple until it retreats, as it will attempt to call nearby Acidic Dumples to its attackers. Once defeated, they no longer secrete acid and are safe to carry by other Pikmin.

In Pikmin: Wide World
The Acid Dumple appears in Pikmin: Wide World as a grub-dog closely related to the Water Dumple and thrives in acid but does not directly utilize it. They may be most commonly found sitting idly in pools of acid, rarely found outside of them, alone or in groups of up to four Acid Dumples. Idle Acid Dumples occasionally move only to reposition themselves. An Acid Dumple will chase after Pikmin and leaders that approach it, and will return to a point near its original resting position once they flee its territory. Any Pikmin it gets close enough to bite will eat them, and leaders in its attack range will be bitten. Acid Dumples move much more quickly in liquids, water included, than on dry land, so caution should be exercised when around them.

Acid Dumples strongly resemble Water Dumples in size and shape, but not so much appearance. They have a round, oblong body with green, leathery skin, and their lips and rear appendages are of a dull lavender color. Visible on their underside are several sets of gills that span the entire body's length.

As they are virtually identical to Water Dumples, the battle strategies that are used against them may also be used against Acid Dumples. Green Pikmin are often necessary to battle them with considering they are almost always found submerged in acid, although those found on land may be fought using any Pikmin type. Charging Pikmin to an Acid Dumple as a first attack is never recommended because they have enough strength to overwhelm and shake off any Pikmin attacking it by jumping, no matter how many are piled on, always following up with bites. However, throwing Pikmin onto an Acid Dumple first before charging Pikmin at it is preferred as the creature will be too occupied by the few Pikmin on it to immediately defend itself against the swarm about to ravage it. Although an Acid Dumple can not be killed instantly by throwing a Pikmin directly on top of it, a Purple Pikmin pound is quite effective against one it directly strikes. Upon death, an Acid Dumple will yield. Aboveground, its body can be taken to either the Dolphin Lander to receive the Master Onion to gain five Pikmin seeds. Underground, its remains may be brought to the Lander Pod to either receive or five Pikmin seeds of any discovered main type, but only if the cave is exited using an escape geyser.

In Pikoblitz
The Acid Dumple is a grub-dog appearing in the fourth and final area of Pikoblitz, Challenger's Canyon. It behaves and looks similar to the Toxic Dumple, but trails acid instead of poison and has green lips instead of pink lips. Battle it as if it were a Water Dumple, but beware of the trail of acid it leaves in its wake.
