Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can send this card from your hand to the Graveyard; Set 1 "Toy Vendor" directly from your Deck to your Spell & Trap Zone. You can Tribute this card, then target 1 "Polymerization" in your Graveyard; add it to your hand. You can only use 1 "Fluffal Bear" effect per turn, and only once that turn.
