Poppy Playtime, The Prototype

Hexproof, Stitch Stitch — Whenever another Bigger Bodies Initiative nontoken creature you control dies, you may return it to the battlefield merged under this creature with this creature on top. (They become one creature.) This creature has all abilities of cards stitched to it and has power and toughness equal to the total power and toughness of itself and those cards. When this creature dies, put all cards stitched to it into their owners’ graveyards. Whenever a Toy Experiment creature you control dies, create {x} Toy Part Tokens, where {x} is that creature’s toughness. {/color#ffffff}
