When indexing the Smurf puzzles, I try to list the included characters.
If there's a sleeping Smurf, that's Lazy. If there's a tripping Smurf, that's Clumsy, if there's a Smurf stealing a desert, it's Greedy, and so on.
Is there a specific Smurf who gives Smurfette flowers?
In the artwork for the Smurfette's House puzzle, the way there's hearts over the Smurf seems to indicate he's a specific character. Also the sweat on the Smurf using a shovel.
