Prehistoric mobs. Idea 2

This is the Scrounger. This prehistoric mob would roam the darkness of caves and the night searching for prey such as zombies and passive mobs. It's a neutral mob that would hide from the player at first, but if the Scrounge was in a pack of more than two (maximum 4) it would start attacking if one of its members was hit . Upon death it would drop the Scrounger claw which can be made into two things, a rage potion which can improve you hits if you were low on hp, or it can be made into a new weapon called a razor blade which has a faster cooldown than a diamond sword but has more attack damage than the iron sword. It would be found in the form of eggs in mineshafts. I suggest adding this mob in a update plz. By MrSneezy1091.
