SlimyBoyos
The SlimyBoyos mod adds an interesting feature to slimes in Minecraft - now they can pick up various items. When a slime finds any object, it picks it up and carries it with itself. The most interesting moment comes when you defeat this slimy creature - it drops the picked up item, which you can take for yourself.
This mechanic opens up new possibilities for gameplay. You can use slimes as a kind of item carriers or create interesting traps and puzzles with their participation.
