This papercraft is Natural Smurfling (Nat, original French name Schtroumpf Nature), one of the main characters of The Smurfs cartoon show, who has appeared on the show on Seasons 3 and 4 as an adult Smurf, and then from Seasons 5 to 8 as a Smurfling, the paper toy is created by Paper Mike.
Nat loves nature to the fullest. He is the only Smurfling willing to walk long miles through a forest, just so that he could view the scenery. It's possible he might be a reference to the animal-loving kids who like exploring forests and other enviromental places.
Nat is also the nicest of the Smurflings, as he cared about Sassette's feelings when Snappy yelled at her during her debut episode. He has shown concern for many things and doesn't like his animal friends to get hurt.
He is a lover of all creatures who's not afraid to put himself at risk to save animals that other Smurfs may consider too dangerous, including Gargamel's pet cat Azrael. He is one of the Smurfs responsible for the creation of Sassette. In his Smurfling form, he is identified by a "country bumpkin" type Smurf hat and a pair of brown ragged pants held up by a single suspender around his left shoulder. [Source: wikia]
