Dweevil family

The Dweevil family is a species of enemies found only in Pikmin 2 that resemble spiders. All members are known to collect treasures, bodies of dead creatures and other objects in order to mimic them or use them for some other purpose.

Most possess elemental attacks, which they do not use unless aggravated, and they are only found underground. The size of smaller Dweevils' bodies make landing a Pikmin on them difficult; they are most easily defeated using Purple Pikmin, which can stun the beasts without landing on them and home in on enemies when thrown. Another easy way to kill all of them (except the Titan Dweevil) is to continually punch them (once for the Volatile Dweevil). This provides a quick and easy way to kill them. Note: If you can be injured by the element it uses, avoid all of its attacks.

Anode Dweevil

Main article: Anode Dweevil.

The Anode Dweevil is yellow and attacks with an electrical discharge, which, like other hazards, will immediately electrocute and kill Pikmin vulnerable to electricity without a chance to save them, thus making it one of the most dangerous common Dweevils. This makes Yellow Pikmin the best choice in battle against them.

Caustic Dweevil

Main article: Caustic Dweevil.

The caustic Dweevil is a blue Dweevil which, when agitated by attacks, releases a blast of acidic bodily fluid in an attempt to drown attacking Pikmin. Therefore, Blue Pikmin are best suited to defeating these bugs. Caustic Dweevils can knock captains down, causing minor damage to them, but their low health and weak attacks mean they pose no real threat to them.

Fiery Dweevil

Main article: Fiery Dweevil.

The Fiery Dweevil is the most common Dweevil in the game. It is a red Dweevil that, when agitated by attacks, will release searing flames that will set nearby Pikmin on fire. This makes Red Pikmin the best choice for combating this creature.

Munge Dweevil

Main article: Munge Dweevil.

The Munge Dweevil is a purple Dweevil that releases a poisonous gas when attacked; this poisons any Pikmin that is not immune to it, making White Pikmin the best choice when fighting these creatures. However, since captains have air filters, they can be beaten easily without Pikmin.

Volatile Dweevil

Main article: Volatile Dweevil.

Volatile Dweevils prefer to carry Bomb Rocks over all other objects; when one sees a captain or Pikmin, it follows it and the Bomb Rock's timer starts. When it detonates, the Dweevil is killed, making the best tactic when confronted with one of these to run away. It is also possible to petrify one with an Ultra-bitter spray and then kill it without it ever exploding. You will at least get nectar, and sometimes a spray. These Dweevils commonly drop from ceilings and are one of the only enemies that can die in the Piklopedia.

Titan Dweevil

Main article: Titan Dweevil.

The Titan Dweevil is the last and final boss in Pikmin 2. It is by far the largest of all known Dweevils, and can attack using the four treasures it has picked up and its arms, the latter of which will do no damage. It is found on the final sublevel of the Dream Den, where Olimar and The President find Louie sitting on top of a mound of treasure. When they approach the mound, however, it reveals itself as the head of the Titan Dweevil and starts to attack.

Trivia

• When a captain uses the Napsack near a Dweevil, it is possible that the Dweevil will pick him up to mimic him. However, because it runs away from captains, it won't sit still once it grabs one of them.
• The name "Dweevil" is an alteration of the word weevil, an insect they closely resemble.
• The Dweevils can still kill Pikmin after it dies; if the health bar reaches zero, an attack animation will still follow. 
• Punching dweevils (with the exception of the Titan Dweevil and the Volatale Dweevil) is a very useful skill,because dweevils have very low health.be warned,though,as their attacks can damage a spacesuit badly.
