SlimyPiston Add-on 1.21+

Simplify work with pistons using the mod SlimyPiston, which offers the ability to turn regular Pistons into sticky ones and back in Minecraft. Just add Slime to a Piston to make it sticky, or use an Axe to remove the Slime and return the Piston to its normal state.

A rather simple addition for those who love using mechanisms and creating extraordinary constructions.
