In Pikmin: Connection of the Worlds
The Ashcrab appears in Pikmin: Connection of the Worlds. It is relatively rare, being found only in volcanic regions, and its body is engulfed in flames. The first time it's hit, it will either leave behind a 5-pellet when aboveground, or three doses of nectar when underground. The second hit leaves behind a random dose of spray nectar, a third hit will leave behind two sprays, and a fourth hit will enrage it. If it is hit a fifth time, it will leave behind a 10-pellet when aboveground or three sprays when underground before it retreats under the ground.

In Pikspore
Ashcrabs are subterranean creatures in Pikspore that feed mainly on ash, soot, and burnt material. They are normally docile except for when being threatened, in which they will emerge from the ground and leave behind fire and black nectar in an effort to flee. They resemble Iridescent Flint Beetles, but with a black body striped with orange, with orange legs and antennae. The first hit yields a random dose of spray nectar, the second hit yields five doses of random spray, and the third hit causes it to shoot black nectar in all directions around it. The Ashcrab with disappear once enough time has passed or if it is hit three times.
