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.
I think you’re exactly right, but what a fun illusion. Now I gotta start tossing them at normal enemies more to see this, I only ever use one on a korok spear for stal-blins
