As we all know slimeball's uses are very limmited. Some players just collect them as trophies, but with my idea it would add a whole knew use to them.

They would be used like glue by right clicking a side of a block with a slimeball then the slimmed texture like on the stick piston would appear. Then objects like sand would no fall if that side was touching a solid block. It could also make it where pistons could move more than one block by glueing blocks together. And possible making it where pistones could move other pistons. And also maybe you can craft them with snowballs to make sticky snowballs that when you hit a monster or player with it they slow down a lot.

Please give feedback.
