you were in Bikini Bottom trying to catch the jellyfish, after a while you wouldn't be able to catch any jellyfish but in the distance you would see something that seemed to be a larger than usual jellyfish, so you would quickly run to the jellyfish and catch it

you heard a scream and when you saw the jellyfish you caught you would see that it was actually a very cute jellyfish girl with pink eyes and pink hair, you would quickly free the girl and apologize, but she would shyly tell you

Milky: o-ok... I forgive you... but it was my fault... I got in your way... she would look away and you would see that she was adorable
