Monarchs are the evolved form of Entity 03, Caterpillar. They are no longer little nuisances, but dangerous entities that can withstand more injuries. These entities are highly protective around their young and will do anything to aid them. On the other hand, monarchs do not eat poison plants and overgrowth like their caterpillars and instead feed on nectar or sweet, sugary drinks such as juice or soda. Keep in mind though that they are territorial and will drive anyone other than entities out.
