I think the Zenyattas have a glitch in their generation code, like they were supposed to appear when a horse licks the salt lick for 80 minutes consecutively, but they don't clear the count so they appear every time the horses lick 80 minutes in total. Because I know my horses don't spend 80 minutes all at once at the salt lick, but I'm always flooded. I just periodically sell off all the unnamed ones; it's a great income source!
I'm not sure how I got the spring gnomes (I have 2). The first year I went to the festival and did the easter egg hunt, with no luck. The second year, my Sims came home with a new baby and almost tripped over the pink guy at the mailbox. I've not seen anywhere that you can get a spring gnome as a baby gift! The other one is similarly mysterious (no pun intended). He just turned up beside the fishing pond one day.
The summer one turned up behind the barbeque grill. I understand he's supposed to be attracted to barbeques and fireworks.
For the winter gnome, I sent the whole family out to build snowmen, aided by the fact the kept getting wishes to build more snowmen. And then poof! there was a much smaller sgnoman in the middle of them.
I've got the cat gnome, too. He caused me a lot of trouble, because the cat always pulled the wrong toys out of the box, so I had to break off and send her to get another toy. Usually, the catnip mouse was the third of the three. After I finally got the gnome, I accidentally discovered that I could have just clicked on the box and selected the specific toy I wanted. :roll: I'll get a dog soon, and see if I can snag the dog and freezer bunny ones. And my teenager has just taken an interest in sculpting, so I hope to get that one was well.
I did trick-or-treating and went through the haunted house many times over three falls and never did get the witch; I'll try just repeating the haunted house this fall and see if it'll work. I've added the wishing well to my game, and will see what I can pull out of that. This game is a 50-foal challenge (thus all the Zenyattas) so I can't get all of the gnomes without breaking the rules, but I want to see how many types I can get.
I also have a vampire gnome from growing plasma bushes, and the laundry gnome from the laundry.
