Unlike other Dweevils, they will start to detonate as soon as they start walking. They are also known to drop from ceilings. The only way to kill it is to run and wait for it to detonate, although if you are in peril you may use ultra-bitter spray to petrify it and then kill it. You will at least get nectar, or possibly spray. It is also the only enemy that can die in the Piklopedia.
Titan dweevil
Mandarachnia gargantium
The Titan Dweevil is the last boss in Pikmin 2. It is a larger version of smaller Dweevils, and only gets its powers from the fact that it has several appliances on it that it uses.In the last dungeon of the game at the very bottom in the Dream Den, 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. It then starts to attack. The Titan Dweevil, before it rises up, resembles a pile of treasure.
