Puffiamo la natura, translated loosely as Let Us Smurf Nature, was an Italian promotional trading card collection distributed through the Conad supermarket chain in 2012. I Puffi is the Italian name for the Smurfs, and the set carried an environmental and nature education theme consistent with Smurf franchise promotions of that era. The collection comprised 162 cards, referred to in Italian collector communities as both cards and figurine (stickers), and was accompanied by a collector album. A special card titled Il gioco della terra (The Game of Earth) was included alongside the standard pictorial cards. Cards were distributed to shoppers with qualifying purchases at Conad stores, a classic Italian retail promotion format used widely by Panini and competitor chains. The set is documented on Italian collector sites including laststicker.com and paninimania.com and has appeared on resale platforms with complete sets and sealed albums still in circulation.
