Do you have the art files from whatever art program you drew the Wigglytuff in? I am also sending the original musician's upload, which has grown a small fanbase if you wanna check it out. Other than that, Thanks for your time immensely!

Here is the original non-reversed song. It is also likely that this song from Mario.exe is pitched down.
