If you wish on shooting stars the next day you will grt fragments and they will continue spawning!

Very cool i did not know that b4

Same with shells throughout the day :)

Twenty star fragments will appear on your beaches when you wish upon them but more can appear if you have guests that wish upon them too. For every five stars that a guest wishes upon, one will appear on your beach too.

With you own and guests' wishes, you can have a maximum of 40 star fragments appear on your beaches.

I just traded stuff and things for most of my star fragments, but I also have quite a few legit ones as well.
