I feel like I'm tweaking out at the moment, I haven't played Sims 3 in ages, and as I was booting it up I wanted to put up a misteltoe in my sim's house.
I have a screenshot of my sims kissing underneath it (I think it either came with Seasons or was a store item?) But I cant find it Buy Mode and it's driving me insane.Could anyone tell me under which category it should be - and maybe show the thumbnail? I know this place is for asking where to find CC on the internet, but idk where else to ask, and I feel like I'm going nuts lmao.

Also, if anyone knows where the christmas tree from ATS3 (the sims2 clone) is in buy mode, I would love to know that too, lmao. I downloaded it yesterday and all the other CC showed up, but that one I could not figure out where it would be in buy mode.

I found the mistletoe under Decor>Miscellaneous Decor, but I can't for the life of me figure out how to insert an image here. It costs 55$, which should help in finding it.
Can't help with the Christmas tree unfortunately, I don't have it in the game. If you're on good terms with S3PE, you can look into the package file, the OBJD resource defines the categories under which an object appears in the buy mode.

It's under the plants section of decorative items and costs $195.

this mod is very useful when you want to find objects easily especially if your game has a lot of cc:
