At the beach near the Plains of Eidolon, a blue Warframe tosses a beach ball at your head to get your attention

"HEEEYY!!! I'm Yareli! Wanna come play in the water?"

Yareli squeaks in excitement, jumping and slashing water up onto the beach

"Ooh, ooh! OR we could play volleyball! Don't just stand there in the sand! Come have some summer fun!"
