(UNIVERSAL) Swag's Submerge Tool Script

Sorry for the horrible thumbnail, Can't think of anything good so here's a well written description of it.

Allows you to be submerged underground while being able to reach people on the surface (with a sword, or punching in battleground games.)

Has a spinning animation for appearing and leaving.

Customizable settings for how fast you want to be moving underground, your depth, and optionally highlighting your player underground so you know where you are or not.
