The Hydro Dweevil, formerly known as the Caustic Dweevil, is a member of the dweevil family that attacks with water, or a similar substance, in self-defense. As is typical of dweevils, it picks up any treasure or enemy corpse it can find, only releasing it when Pikmin attack.

Attacks Drowns Pikmin

The Hydro Dweevil appears in Pikmin 2: New Year as a member of the dweevil family. It flees from Pikmin and leaders that approach too closely, and when attacked defends itself using a shower of water that endangers all Pikmin in its range except Blue Pikmin. Like other lesser dweevils, Hydro Dweevils will pick up and carry around objects, such as treasures and corpses, they are in the vicinity of.

Hydro Dweevils much resemble Caustic Dweevils but with a more vibrant skin tone in addition to black markings on their legs.

The only threat posed by a Hydro Dweevil lies in the water it defends itself with. Unless the creature is carrying an object, in which case the object must be removed before damage may be inflicted, it can be easily killed by throwing Pikmin onto the underside of its body. Purple Pikmin are especially effective against Hydro Dweevils because of their pound attack, which can stun any in its range and instantly remove an object one is carrying.

Caustic Dweevils appear in Pikmin 251. They are unchanged from how they are in Pikmin 2.


Olimar's observations

This Dweevil is another one that hasn't changed much this time. They do seem to be quite uncommon though. Enemies that attack Pikmin with water are quite uncommon in general. I wonder why that is?

Amanzi is the Hydro Dweevil that appears in Pikmin: Antarctic Survival. She has the ability to use water through the use of her innate mist abilities.

To do: Information on this character

Amanzi's name is the word for "water" in the Zulu language. Her name also draws a potential connection to Anansi, an Akan folktale character commonly depicted as a spider.

The Caustic Dweevil is a returning enemy found in Pikmin: Decayed Leaf. This Dweevil acts just like most others, taking treasures and corpses and running off with them. If attacked, the Dweevil will spit out a wave of water which can choke non-Blue Pikmin. Cactus Pikmin can benefit from the water spat out of the Dweevil. Weighted Pikmin are immune to the water. If a Dweevil walks off a ledge and into a pit with a treasure, the treasure will appear safely on the ground.

The Dampening Dweevil appears in Pikmin: Dual Worlds. This species of dweevil acts a bit differently from its Pikmin 2 incarnation in that it ejects balls of water from holes on its mandibles at high speed, similar to the Titan Dweevil's Monster Pump attack. Its range, as well as the number of projectiles it can shoot in one attack, is significantly reduced, but still quite large. The amount of time between shots is increased to about one-fourth of a second.


Olimar's notes

This species of dweevil is notably different from the caustic dweevils of my second venture to this planet. Its projectiles are much less acidic, in addition to them working differently. It seems likely that the caustic dweevil at some point diverged into three species, creating the roughly neutral dampening dweevil, the frosty hoar dweevil, and the even more acidic sulfuric dweevil.

Attacks Drowns Pikmin

The Dousing Dweevil is a species of lesser dweevil appearing in Pikmin: Wide World. It explores its small territory on dry land or in shallow water, by itself or with other creatures including its own kind, periodically idling in place, and flees from approaching danger such as Pikmin or leaders. When near an object that requires the strength of up to ten Pikmin to carry, a Dousing Dweevil will scurry towards it, lift it with its pincers as it scrambles underneath, and then proceed to carry it around on top of its body, holding it firmly using its pincers. They typically are already equipped with an object. However, they do not interact with any bomb rock variant, and in fact avoid them, perhaps aware of their destructive potential. While alone and in possession of an object, they fold their legs underneath themselves to sit down, also burying them if the terrain under them is soft to better conceal themselves. They will do this regardless of whether they are on land or in shallow water. When the object a Dousing Dweevil is holding is nudged, it will be startled out of its disguise and begin to flee. Dousing Dweevils can take unattended objects as easily as they can any being carried by Pikmin or dragged by a breadbug, leaving either stranded from the object. Dousing Dweevils also attempt to pick up leaders that are lying down, though leaders they do that to immediately get up. In caves, Dousing Dweevils are not always initially present on the ground, as they may use strands of their silk to rappel down from cave walls when Pikmin or leaders come near. Until they reveal themselves, they can not be seen in the darkness even with the HocoPad's camera function, but if the ceiling is low enough, the camera's flash may startle them and send them plummeting to the ground below. Dousing Dweevils that rappel down are never already holding objects.

Dousing Dweevils are fairly-sized spider-like insects that have a blue exoskeleton, a round body, a pair of brown eyes above two purple eyes, four slender legs that each end at a fine, dark point, a pair of arms that dangle from their body when in a neutral position and terminate in a pair of pincers, and a pair of mandibles that each have green bristles on the outer side of their ends.

Although easy to kill, Dousing Dweevils can be problematic to hit because of their small frame and are even more so while carrying an object, which inadvertently shields them from harm. To remove an object from its possession, simply throw a few Pikmin, or a single Purple Pikmin, at it or harm the dweevil sufficiently. Depending on the choice, the dweevil will either lack the strength or endure too much pain to continue holding the object. The only time they attack is in retaliation, during which they stand still as their body begins to drip with water, endangering inapt Pikmin even then, before releasing a deluge of the fluid under their body. The water splashes around the Dousing Dweevil, putting nearby Pikmin at risk of drowning, and on land, also leaves a harmless puddle of moderate size that eventually and gradually dries from the outside in. The puddle only presents a threat when in contact with electricity. The optimal way to defeat one is to stand under it and rapidly throw Pikmin, preferably Blue Pikmin because of their water resistance, at its softer main body. Attacking its legs also works but is far less effective as they are very damage-resistant. The fastest way to take down a Dousing Dweevil, and any other lesser dweevil, regardless of it carrying an object, is with Purple Pikmin; their pound removes objects from its grasp and the impact of the Pikmin landing on it slams the dweevil's body to the ground, instantly killing it. On top of that, Purple Pikmin pounds always stun any Dousing Dweevil caught in their range. Upon death, they spasm shortly before inverting themselves and curling their legs, but if killed by a Purple Pikmin pound, they simply go limp with their legs outstretched instead.

In ultra-spicy difficulty, Dousing Dweevils take half as much time to execute their retaliatory attack. Their attack also splashes farther and leaves larger puddles, having a slightly greater range overall.


  • PWW Data file icon.png Data file #1 (all difficulties): Dousing Dweevils can release a deluge of water that leaves a harmless puddle. Don't get splashed!
  • PWW Data file icon.png Data file #2 (ultra-spicy difficulty only): A Dousing Dweevil's water splashes a fair distance and leaves a large puddle.

Olimar's comments

PWW Captain Olimar icon.png The fluid expelled by the dousing dweevil when threatened is nothing more than perspiration. Such a defense mechanism is ineffective against creatures that don't mind getting wet or are in frequent contact with water.

Shacho's comments

PWW President icon.png This creature could supply much-needed water to the people of Hocotate. I could bottle it and then market it as dweevil juice! I haven't tasted it, but nobody has any problem with it, so I say it's fine. Maybe nobody will notice the smell...

Marie's comments

PWW Marie icon.png Dousing dweevils are great to have at pool parties, water parks, or the scene of a fire! Just give them a tickle, and prepare for the oncoming shower. I just can't seem to explain the water's musky scent...

Louie's comments

PWW Louie icon.png The insect's lean meat is made juicy and tastefully salty by its fluids. To separate the salt from the fluid, simply evaporate it.

Dolphin Lander's comments

PWW Dolphin Lander icon.png There seems to be a lot of controversy over the dousing dweevil's sweat. That's literally what it is, even if a lot of it is released at once... and through sheer will.

Olimar's notes

This dweevil seems to be similar to Blue Pikmin in many ways. They both have a liking for water, and they both have amazing strength. Perhaps, somewhere, there are Dweevilmin! Probably not...
