Durmite is a caterpillar-like boss found inside Bowser's body in Mario & Luigi: Bowser's Inside Story. The creature wears a ribbon on her head, has angry eyes, and a funnel-like snout, similar to Birdo's trunk. Her body is somewhat similar to a Wiggler, only with small, white feet, and a white/yellow line splitting the wiggler-birdo's colors. One half green-blue, and the other side pink.
Durmite came from a very large carrot of a Wiggler's garden that Bowser was forced to eat the vegetable and then battle the Wiggler. A bit after beating the Wiggler, Bowser got a major stomachache that came from Durmite. The Mario brothers must defeat Durmite and so continue their adventure. Durmite reveals that she is actually Wisdurm, the guardian of the first Star Cure, after Mario and Luigi catch up with her in the Energy Hold.
In battle, Durmite attack the plumbers in many ways. One of her attacks turns her completely red from anger, like wigglers do, and charge at Mario or Luigi. The plumbers can counter this attack using their hammers, dealing damage to Durmite. However, Durmite can use keen attacks, such as spiting a sticky string from her snout to capture either Mario or Luigi and eat them. After eating the victim, Durmite can spit out her meal for an attack against the heroes or sometimes release the victim from her rear to hit the target to the back and lose speed then.
Durmite will summon Biffiduses to fight for her, which she can devour and use their spears to shoot them towards any of the brothers with her snout. These attacks can be avoided using a timely jump. Durmite will sometimes summon a straw from her mouth, which allows her to regain her health. The brothers must take a quick action on destroying the straw which stops Durmite from sucking nutrients.
The Straw is a heart-shaped object that Durmite uses in battle to steal Bowser's HP. It has no physical attacks, but is merely used by Durmite to recover HP. The Straw is a light shade of purple, and is a part of Durmite, acting as a proboscis.
Whenever the Straw appears, a tribe of Biffidus usually appears to defend Durmite and attempt to distract the Mario Bros., while Durmite recovers HP. The Straw does not need to be destroyed, however, it can be, and if done so, it will prevent Durmite from regaining HP (until Durmite uses it again).
 Durmite X
Like many bosses in the game, Durmite also has an X counterpart called Durmite X which is a boss encountered in the Challenge Node inside Bowser's body. It battles just like Durmite, but has stronger attacks. Biffidus X also appears. Durmite X can still use her straw, but it is now called Straw X and will recover 80 HP as opposed to the 40 HP the regular Durmite replenishes.
