Colored slimes and slime etractor tool

One simple thing is that slimes should be colorful, but they should come with their own unique challenges! like maybe they can put mobs inside to deal more damage, of they hit and give you an effect! but going through doesn't just mean you just get colorful slimeballs and blocks, using 4 colored slimeballs surrounding an ender pearl you get the slime etractor! this tool sticks the thing touching the ball getting attracted to the player! but hits 3 and a half hearts as well, and pulls better than a fishing rod!

that's all my slime ideas right now!
