Hook Mob (in dripstone caves)

A mob with four legs (each witch a talon on the end) that would use it's tongue to swing from high-up dripstone. It would have a long face (like a crocodile) and a scaly, dark green body. You could spawn the creature by using Creature bait. It would be a tanky mob (30 ish hp) and have two attacks The first attack would be a vicious stab from its tongue with about 10 blocks of range. It's second attack would be a swipe witch it's talons. This attack would be a mid-damage attack witch large knock back. Upon slaying the Hook (the mob in question), you would either get leads (meant to represent it's tongue) or, rarely, it's talons. Crafting the talon with and arrow would give you a grapple arrow, allowing you one use to swing from any dripstone on the ceiling. No fall damage would be taken after using the grapple arrow, but the arrow would also do no damage. Alternatively, you could use the talon to craft a scythe. The scythe would have an L2 ability (with a cool down) in wich when you hit something, the direction of the knock back from the scythe would be determined by wich way you were turning when you hit something. For example, hitting a player in the middle of turning right would move the target player to the the right. Standing still or moving forward would cause the knock back to stay the same as a sword. The scythe would also have an enchantment that increases the L2 abilitie's affect, knocking the player farther to the side.
