Scout Slime

A Slime variant capable of holding about a stack of items (64) in its inventory as it purposely looks for junk dropped by the player or mob drops. The scout slime has only two sizes the medium size and the small size, the small size is capable of holding about 16-34 items while the medium slime can hold about 34-64 items but if it finds non-stackable items like swords or enchantment books it will not pick up anymore items until it has been collected by the player. The slimes mechanic shares the same as a bundles mechanic while being semi-tamable (meaning it won't follow the player around unless it's given certain conditions and nor will it teleport to the player but it won't despawn, but it will wander within the radius of it's "home position" to look for random items to collect and as for the mechanic it's pretty much a walking bundle). Scout slimes are a little uncommon and are somewhat fragile as to not minimize the Bundle item and will spawn in mineshafts and lush caves, if the slime is damaged it can be healed with slimeballs.
