The Snail & The Znail

The Snail is a new, mostly ambient mob that has really only one purpose. I would spawn in all temperate biomes on dirt, grass, mud, and moss. Behind it, it would leave a trail of mucus that could be applied to single sides of blocks and would essentially act like glue, keeping them together, like when using pistons. When killed, they have a 50% chance to drop it's shell, which can be crushed into what's called Crushed Calcium. Also, they can be tamed with lettuce from this post. This has no inherent benefit other than being cute. I made a model for The Snail and The Znail (a zombified snail that burns in sunlight and spawns at night in temperate biomes, giving it a shell will prevent it from burning), which is entirely ambient but can also be tamed.
