A slimy tentacle like apendage that allows grapplehook/swinging features (two allows for spiderman swinging)

Also allows for mob manipulation/moving mobs , players and entitys (sorta like a gooey gravity gun)

If interacting with item drops it will flick out and grab them and put it in your inventory

Addtl design notes/food for thought

1. Attach it to a target block in range (TBD).
2. You can pull yourself to that block.
3. You can push yourself off of that block.
4. While attached and relatively near the target block, you can jump a few tiles up.
5. if the target block is below you, "stilt" for a high jump
6. Left and right click gives you two grapplers independently. When attached with both, motion and position attempt to equalize
7. Attaching the grappler to an entity lets you manipulate it radially/spherically, aligned to a sphere with a radius of your distance to that entity. MATH ENSUES.
