"If the medium slime became a giant slime in just a few minutes, what do you think would happen to a massive slime if it eats a bunch of giant slimes?" Remey was trying to think of the worst case scenario. She knew that she was not very useful against the slime because of its decaying slime body.
"If it does that we are going to be in for a much worse time. I know the brown mud slimes become a monster called a swamp thing. It basically lets water plants live on its body so it can absorb nutrients. They can be the size of a house and are nearly impossible to destroy since they can heal by making the plants grow faster. Not sure what would happen to a purple decaying slime though."
Creation is hard, cheer me up!
