In Pikmin Evolution
The Ironhead Crusteroid is a species of Crustelore appearing in Pikmin Evolution. They resemble large crabs, their shells resemble solid iron and they appear to be clad in it almost like an impenetrable armor. They have large, flat, and pronounced heads and have a small pair of claws unfit for combat. They are completly harmless, lacking any way to attack you or your Pikmin, but likewise your Pikmin army can't harm it back as any attack will just get bounced off due to the Crusteroid's thick metal armor. There is no way to remove this armor, as not even the most corrosive acid can melt it down, in other words they are unkillable. This is why the Crusteroid is harmless as what is the point of great offenses if you can tank through the damage with no problem. The Ironhead Crusteroid spends it's time blissfully eating seeds and pellets with it's fellow Crusteroids, when they encounter a large creature they get startled and run away despite their defensive advantage. The large head of the Ironhead Crusteroid is able to be walked on safely by small creatures, some creatures like the Wollywog like to ride on the Crusteroid as a way to both sunbathe and gain a advantage in the air. Likewise Pikmin are able to ride these crustaceans as well, allowing them to cross dangerous terrain such as acid much more safely. Of course you can't just ride Ironhead Crusteroids, as they can get startled and shake your Pikmin off, rather you need to feed them first in order to persuade them to assist you. Ironhead Crusteroids come in 3 sizes, which dictates the maximum amount of Pikmin they can carry, small ones carry 25 Pikmin, medium ones carry 50 Pikmin, and large ones carry 75 Pikmin, if you exceed that amount the Ironhead Crusteroid will flip over and bury away, leaving you unable to use one for an entire in-game day. Ironhead Crusteroids can be bred in settlements by luring them to traps with pellets, by breeding them you can produce metal ore without heading out to collect supplies, additionally with the Creature Call function you can summon one to act as a makeshift platform for your Pikmin. Summoned Crusteroids will only come in the medium size, so one must remember that limitation if they want to take advantage of these creatures. Overall Ironhead Crusteroids are a very helpful creature and they offer a simple but useful function for your team to use.
