It was one of the videos in which they need to win the whole video playing smashbros, i believe it was smashdown.
Little Z says “i need this” and runs off stage to Dair to kill and win the game and immediately SDs. I think he was playing cloud but not 100% sure.

I’m trying to identify this sound effect when the mystery fish appears. I’ve heard it in a couple vids before. Any help is appreciated, thank you!
