@ungewichtet - I love this, great fun - thanks for posting. I was the person who said Chess pieces are my adult Smurf’s! And they definitely are!! 😄
Further, Smurfs (and branded stickers) were the first things I remember collecting. While smart people were collecting coins and stamps - I had my Smurfs. Sadly, in my early twenties I gave my collection to a nephew in NZ and his mum (my sister) sold them many years later … bummer!
@Powderdigit - Nice you passed them on to your nephew, sad they are gone now. But what can you do? Later, when you will say that smurfs are your old age chessmen, maybe you will recall this thread and think ach ja, that was when it all started over again.. 
Let me add something on the composition of the blue and the blue side:
My choices were inspired by the original setting of the smurf village dans le pays maudit as given in the old Peyo stories in the comic books of the 1950ies and 60ies. The smurfs are a friendly community of 100 individuals led by le grand schtroumpf (the great smurf). They live self-sufficiently in the woods in mushroom houses and like food, dance and music. They're quite social. Chess wouldn't come to their mind but I find they can play it.
The first smurfs made were rather simple, which makes for good chess pieces. I took le grand schtroumpf ("papa"; literally: the great smurf) as one king and the gold smurf (who took charge in one adventure when the great smurf left his smurfs alone for a couple of weeks) for the other king.
For queens I took two of the three early smurfette versions. (In 'la schtroumpfette' (1966) an evil sorcerer makes and sends a black haired girl smurf to shake the peaceful life of the smurfs. She is transformed into a blonde by magical effort by the great smurf. Either way she is a big challenge, but her black haired time never was portrayed as toy figurine, thus two versions of the blonde.
For the bishops, for one side I thought of the french fous: The smurfs have a joker that, among other things, keeps handing out explosive presents. He is even is trialed for this once, after fooling the king- hence the prosecutor as his partner bishop. The other blue side has the arts as bishops: The flutist and the painter (Man Ray made the bishops amphoras and the knights violins). Sound and light travel fast as bishops and couriers!
The 2x2 knights I take from two stories: In 'le cosmoschtroumpf'(1969) one smurf wants to fly. He tries hen's feathers and builds a rocket to fly to the moon. On the 'moon' (an old volcano) he finds orange natives (his smurf pals transformed by a magic soup). They do fantastic jumping. In 'les schtroumpfs noirs'(1963) a black bee stung and blue smurfs turned black. The blacks bite- and do great jumping doing it.
The rooks, I settled for one pair of rooks consisting of craftsmen: the blacksmith and the mechanic. For the other set of rooks I settled for le schtroumpf costaud lifting a dumbbell- a stronghold smurf- and for the cook- presenting nourishment of home&castle or silo.
The pawns are your everyday smurfs: Each and every one a wonderful specimen with lots of things to do.

I took part in the nice 'how did you start collecting chess stuff' thread. One pittoresk collector said chess pieces were his adult smurfs. I laughed and thought, well, once upon a time smurf figurines used to be for old and young.
They were first created as comic book characters in Belgium in the late fifties by Peyo- Pierre Culliford. Long adventures, short stories and one-pagers. The figurines came under way mid- to end-sixties. The German producers had a sculptor to do the adaption and develop smurfs following the characters from the comic books. I loved them as a child. Later I still loved them, especially the early ones that came from the original setting and stories. I always thought who was this blue Michelangelo and in the end it turned out to be the artist Eva Zippel. I don't know if she varied her style or when did other people join her, but she set the tone for what smurfs felt like as toy figurines.
Look at the first 50 or 70 or so smurfs, and you will probably like them. They are very collectible, too, because their success in the 70ies made them a mass product, still easily available today. There are only very few expensive smurfs from that period, and they, in any case, look good even without their eventual breakable, loseable or uproughable details.
Anyways, here is a chess set I put together mit meinen Schlümpfen:
