Decomposer

The Decomposer is a fat grub creature that has 20 health.

It is not hostile, and can be found around Mushroom Islands.

It can be tamed using Alluring Powder. When tamed it can be given ferns, bones, rotten flash, poisonous potatoes, etc. to produce Bone Meal or Growth Meld. Also, zombies will avoid them in a future update.

When killed it drops nothing.
