Everything is all made up, except for Mario & Luigi. I voiced all of them (obviously :D). Took me all day 'cause of writing the script & searching thousands of free music & sound effects. most sound effects are from Mixcraft. I'll place a link under on where you can download the songs that are in this Voice Demo.
The characters you'll hear are the characters from my comics that been on-going since 2005. to check out my comics, just go to my Newgrounds page & click the deviantart link
