Listen to Ozzy Osbourne on iHeartRadio

Ozzy Osbourne is expanding his audience.  

Rolling Stone says the legendary Prince of Darkness has signed on to voice a role in a Nick Jr. show.  Ozzy says he agreed to portray Sid Fishy on"Bubble Guppies" because of his two-year-old granddaughter, Pearl.

Ozzy says he "can't wait to see her reaction" when she hears grandpa's voice "come from Sid Fishy's mouth."  Sid Fishy is described as a "rock and roll fish who loves being rotten." 

A rep for the show says the character carries a tank of green liquid of "stink sauce" made of things like rotten eggs and smelly socks.  The rep adds that Fishy's goal is to "use the stink sauce to cover Big Bubble City and all its citizens to make them stinky." 

An air date for Ozzy's episode hasn't been announced yet, but it's expected to debut next year.
