Limax

'What The Deuce?!' Brainstorm(A Cerebrocrustacean)
The Limax are shape-shifting slime aliens from an unknown world. The Limax thrive in conditions of fire and heat, hence why they chose to begin their invasion plans in retirement communities situated in the middle of a desert in the summer months. They come to Earth to collect elderly people and devour them; they indicate that young people don't taste as good. The Limax seem to have a hive mind, being able to coordinate throughout a large area without any direct contact, though they do speak to each other. The Limax can merge with each other to form one gigantic Limax. They melt when exposed to cold water, which evidently is poisonous to them.
