Challenges and Collections

I’m not sure that you can do the challenges again, I think I once triggered the sugar skull one (don’t remember how). The eggs you might get if you have seasons and do the Easter egg hunt tradition. The items are all in buy debug, but it’s obviously not as exciting to get them that way.

Thanks @Kita5399 - wasn't aware if I had sims do the Easter egg hunt that they could collect eggs for the collection. I'll check to make sure I have it on the calendar

You can get the eggs if you make a holiday and "hunt for eggs" as a tradition.

You can get the sugar skulls by offering up to the dead (I forget the exact command but it's still there if you have a recent grave on your lot and it will spawn a "day of the dead" NPC for you to interact with and ask for a skull).

I've gotten magic beans in rare seed packets and you can buy the stump in buy mode, in the outdoor activities, no cheats needed.

You can get the magic beans by buying seeds on the computer. They come in a pack, not sure which one, magical plants, rare plants, etc. (not the regular seasonal/stater packs). For the sugar skulls, I read somewhere around here on the forums that you can get them by doing an interaction with the tombstone, remember the dead or something, I forgot what it was. You can also occasionally find them at the flea market.
