Husks should spawn in the beaches

Husks are a mob with great potential, but are to rare to be noticed

However, if they are added to the beaches they could bring new threats.

Other ideas:

Husks hunger should last longer and be more powerful

Husks should be similar to the mechanic "you may not rest as there are monsters near by", this would work so that turtles will not breed if a husk is near them.

Finally, husks should be able to sometimes spawn with a wooden sword, wooden pickaxe, or wooden axe.
