Snail

The Snail is a rather rare critter that only spawns underground. It can be caught using the Bug Net to be carried around in the inventory and released later, or crafted into a Snail Cage to be placed as an animated furniture item. It cannot be released once crafted. Its counterpart is the Glowing Snail.

A Snail Cage occupies a 2x3 space. The Snail inside may follow the following patterns randomly:
 * Hide inside its shell
 * Try to climb up to the ceiling of the cage, but fail and fall down again
 * Make a whole loop around its cage succesfully
