Simple! Remix the project, click see inside, go to costumes, then change the sprites to match you or any ocs! And you can also change some of the code to make the animation better if you want. The original one by SquigglyTuff was taken down due to drama from the original mod, so I remade the sprites! Enjoy it...hopefully not for a limited time. (EDIT) Upon SquigglyTuff's message, I decided to watermark this work of mine. Just in case SOMEONE tries to steal it as their own. I doubt that would happen due to the little fame I've got, but better safe than sorry.
Thanks to @SquigglyTuff for creating the No Villains engine, and thanks to @Captain_Animations21 for salvaging it in his remix, which is right down here: https://scratch.mit.edu/projects/642504549/ Lazerbot is the creator of Tails Gets Trolled, and No Villains is one of the songs
