What event is this pet from?

[Dino Nugget]

I'm sure there was a thread for this but I can't seem to find it. Anyway, I got this pet from the pound and I know it's from June 2023 but it's definitely not a litter pet. It's just in June, not any of the event tabs. Does anyone know if there was a mini event or anything in that month?

This outcome was released during the World Ocean Day mini event!
Past mini events that don't have their own archive tabs have been compiled in this guide. ^^
