The 12 Days of Simsmas - Day 6 - A Miracle on Komorebi Street.

@LixyQuinn170 If you haven't collected one before, when you encounter them anywhere you get the option to make a wish or collect them. If you choose to collect them they don't like it, they'll get angry and curse your Sim with a negative moodlet for a little while but the Sim will suddenly find a little doll in their inventory. This Sim has collected just about everything in the game so she had to have one lol (well at least I told her she had to have one). I don't usually collect them as a rule because they're so sweet I forget they're technically just pixels!
