Shit Nuke
The Shit Nuke is a script created by a Anonymous user, It spams the canvas with brown ANSI Chars and poop emojis. I (Guest-1052) don't have any screenshots of it but I (Guest-1052) made a recreation of it a while ago, It's pretty similar.
The Shit Nuke explodes when a timer ends, The script was run on spawn once and the anon actually responded to my (Guest-1052) remake saying its really close to the original shit nuke.
