This happened exactly one time in the 200 hours I’ve played. Not that I use Dazzlefruit all that often. Maybe this is super common, but I haven’t heard anyone else mention it. I think it’s a cute little Easter egg they added, like how skydiving at night sometimes makes Star Fragments appear right behind you.
Korok weapons have the reuse fused item ability, so after a brief recharge the dazzle fruit is god to use again!
