Jellies are a type of soft, squishy food that often has a jelly-like consistency. They can be made from a variety of ingredients, but the most popular ones are made from animal proteins – like pork and chicken. To make these jellies, the proteins are cooked until they form a thick, Gooey substance called gelatin.

The process of turning from a gelatinous jelly into a hard shell is called exogenesis. The steps involved in exogenesis are as follows:
1) The slug secretes a sticky fluid that helps it adhere to other objects. This fluid contains ammonium ions and proteins that help the slug form clumps.
2) The clumps grow and fuse together until they form a thin sheet-like layer over the slug's body.
3) The layer becomes harder as more glucans areadded to it. This process is called gelation.
4) The layer eventually hardens into a shell and the slug can move around without worrying about breaking it.
Snails have a pretty cool process of turning from gelatinous jellies into hard shells. They start out as soft, squishy blobs that are about the size of an orange. As they slowly digest their food, this gel slowly thickens until it becomes too hard for the snail to swallow and it pops out of its shell. This process takes around two weeks and is another example of how animals can adapt to changes in their environment.
