MARIO, the Koopa, and the Goomba belong to Nintendo. Sound is from Invader Zim (Battle of the Planets episode) and the Starman (Invincibility) Theme from Super Mario Brothers.
The guy chasing the goomba is MARIO. I can see where people might think this is Luigi, but in my style, I draw Luigi much taller and thinner as he actually is... The colors Star MARIO flashes are the colors from the original NES. Coincidentally, those colors are also used in the Super Smash Bros. games.
