Sun
When it’s in trouble, its eyes moisten and begin to shine. The shining light attracts its comrades, and they stand together against their enemies.

It’s awfully weak and notably tasty, so everyone is always out to get it. As it happens, anyone trying to bully it receives a painful lesson.
Ultra Sun
They’re weak, so they move in schools. However, they can also often be seen all alone, having strayed from the school.
Ultra Moon
When it’s in a jam, its shining eyes attract others of its kind. The light from its eyes is visible almost 25 miles away.
Sword
Individually, they’re incredibly weak. It’s by gathering up into schools that they’re able to confront opponents.
Shield
When it senses danger, its eyes tear up. The sparkle of its tears signals other Wishiwashi to gather.
