Matryoshka Dolls would be a container item, similar to Capsules and Crates. They could be picked up and thrown, damaging foes that they hit. Doing so will cause the doll to break, revealing another, smaller doll inside. Attacking a Matryoshka Doll will also break it. This cycle will continue, the dolls getting smaller and smaller until finally, an item pops out of it. What item comes out depends on how big the final Matryoshka Doll was: smaller ones hold weaker items like Green Shells and Smoke Balls, while larger ones hold powerful items like Hammers and Maxim Tomatoes. How many times the Matryoshka Doll breaks before revealing the item also varies, though it will always be between two and eight.
