well in my real life mario game the cute big catapilar called the wiggler are still big in my real version and still a little cute but these catapilar are one of mutated insect specie of the other world they are now way bigger then normal catapilar and there fake flower on the head was a normal evolution is was how they catch smaller insects when they landed on it they turn very fast to eat tere prey. now that there bigger and stronger you can easely be a prey. they are easy to avoid with certand power ups its eftently best to avoid cose if you make them become in protection mode or attack more there blood prechure makes them turn all red that meens you better run or fight them if you have to just dont make them red it makes them way more predatoriest. there not one of the mutated specie that obeys king koopa bowser cose there still just insects but bowser does capture some to use them to attack villages before bowser send in is main troops there they will be more agressive and very hard to avoid but those in nature are more friendly if not treten.
