The Volatile Dweevil (サクレショイグモ) is an enemy in Pikmin 2. At first glance, it appears to be Bomb Rock with legs, but are actually Dweevils that have picked up bomb-rocks, much like how other members of the Dweevil family pick up treasures and corpses; unlike other members of that family, Volatile Dweevils are known only to carry bomb-rocks, and are never seen without carrying one.
A Volatile Dweevil's Bomb Rock will start the count-down fuse as soon as the creature is startled, it will chase captains and Pikmin until the bomb explodes, killing itself, and anything else caught in the blast. With that in mind, the best way to deal with a Volatile Dweevil simply to run away from it until it blows up. They cannot be attacked unless petrified, which also freezes the bomb-rock in mid-detonation, making it useful in an emergency but often impractical because it wastes a spray on an enemy which will drop no corpse.
In terms of gameplay, Volatile Dweevils are more-so hazards than enemies. They can unexpectedly drop from the ceiling and are often found around treasures, making them extremely dangerous to Pikmin attempting to retrieve the treasure.
Volatile Dweevils are roulette options on 2-Player Battle. When activated, a Volatile Dweevil drops onto the opponent player, and begins to detonate. It is best to use this power up when the opponent is preoccupied with many tasks.
"The volatile dweevil is one member of an insect family known for mimicking objects by carrying them on their backs. The dweevil family exhibits a most unusual characteristic whereby the creature's behavioral patterns actually change based upon the object the creature carries on its back. The volatile dweevil has one of the most potent attacks of all species in within the dweevil family, due to its habit of carrying explosive devices. Approach with caution and/or body armor!"
"This scorching species combusts upon contact with the tongue. Only edible by the adventurous and asbestos-tongued."
Nintendo Player's Guide
"Bomb-rock-carrying spiders charge at your Pikmin and pilots as their explosives are triggered and the countdown has begun. When you see a Volatile Dweevil, gather your Pikmin and run. The good news is that once a Volatiles Dweevil's bomb rock detonates, the creature will be history."
Typically, Volatile Dweevils will fall from the ceiling in certain caves, so always be cautious in those caves. If a Volatile Dweevil drops down, it is best to stay near it long enough to begin its count-down process, and then run away to allow it to explode away from your Pikmin. Dealing with Volatile Dweevils while carrying treasures is a little more difficult, as it makes you call your Pikmin back, often more than once. When carrying objects back to your ship pod, and a Volatile Dweevil falls upon your group, you can lead the Dweevil away from the Pikmin with your captains. Just make sure to get out of the way of the explosion, as it deals a decent chunk of damage to your leaders.
Start up the Piklopedia. Then go to the Volatile Dweevil archive. First petrify it, then wait. Right before it breaks free, petrify it again. If it is done correctly, Bomb Rock should be turned into stone. Throw Pikpik Carrots at it, and if they hit it, it will wake up, but the bomb-rock won't activate. Before the rock breaks free, petrify the Dweevil, and only the body will be petrified, but the bomb-rock will activate. The bomb-rock may even explode and kill the petrified Dweevil.
- The Volatile Dweevil is one of only two enemies that can be killed in the Piklopedia.
- It's Piklopedia entry states Dweevils copy the "behavior" of the objects they carry, hence Volatile Dweevils blowing up like the Bomb Rocks they possess.
- Although can be rarely seen, it has a black head.
