101 Smurfs, one of them a woman. There's either a lot of gay smurfing going on, or it's the hole.
(Incidentally, did you ever notice that no matter how many new Smurf characters they added, there were always 101 Smurfs? I'm not suggesting they practised ritual sacrifice to keep their numbers at a specific level. I'm just saying it was 101 before Smurfette and Baby and 101 after Smurfette and Baby.)
They have a tesseract for that. Which makes sense when you think about it, what with their entire village being near only a single human habitation, and that being a wizard.
