Tentacle Zombie

The tentacle zombie would spawn in the Nether Tentacle biome (click here for more info). It would look like a zombie, but one hand is a tentacle and the zombie is a more reddish. Here is a picture of what the basics of it could look like:

It would have the same statistic of a normal zombie, but it is fire resistance. Because of its large tentacle, it can hit the player from 10 feet away. If it hits the player with its tentacle it pulls the player into the zombie, where it can use its fist and deal an extra 1 heart of damage.
