5th Glitch on the list. 1.World of Light Mr. L Crash (No Footage) 2.Crowd Screech (Video on Smash World) 3.Custom Stage Camera (No Footage) 4.Ascending Blocc (Video on Smash World) 5.CPU Level 0 (Read Notes and Credits)
Smashdown doesn’t allow replays, but I’m pretty sure Level 0 is either Level 1 or the level that the Quickplay Practice CPU is on. Shoutouts to Pixelated Players and @Lucas919 for finding out how to activate the glitch! Go into smashdown, make it 2 players (both human) start a match, make P1 win, on fighter select screen, go to the switch home menu, disconnect p2's controller, then decide winner of smashdown using current standings, and re-enter Smashdown.
