Mesoid family

The mesoid family consists of tripodal insects.

Extinguishing Elongflea
A roaming creature that does not actively attack Pikmin unprovoked, but leaves behind bubbling liquid with every step, making it a danger to non-Blue Pikmin regardless.

Jewelbomb
Smaller Mesoids whose back leg is adapted into a prehensile claw, which they use to intercept bomb rocks placed by Pikmin and roll them back at them.

Proto-Legs
Large predators that share characteristics with the true arachnorbs, such as their habit of leaping onto passing Pikmin from above. They are able to scare Pikmin into a panic, then eat them at a leisurely pace.
