A children's animated show named Bubble Guppies is not the first, or hundredth, thing one would equate with a man who once snorted a line of ants with Mötley Crüe and bit the head off a dove. But, Ozzy Osbourne is set to guest-star on Nickelodeon's popular preschool series as Sid Fishy, a "rock and roll fish who loves being rotten", reports Jason Newman for RollingStone.com.

Unlike the more wholesome residents of underwater city Bubbletucky, Sid Fishy sports a red mohawk, eyebrow and fin rings, gold tooth and slime spray to wreak havoc on unsuspecting guppies. The Prince of Darkness tells Rolling Stone he was drawn to the character because "I’ve always smelled a bit fishy."

When asked to elaborate on the contents of Fishy's container, a representative for the show replied, "The green liquid is Sid Fishy's 'stink sauce' made up of different smells such as stinky socks and rotten eggs. He wants to use the stink sauce to cover Big Bubble City and all its citizens to make them stinky." It is unclear which characters, including Mr. Grouper, Mr. Grumpfish and any of the residents of the Bubbletucky Zoo, will be affected.

In a separate episode, RuPaul will also star as RuPearl, a "charismatic snail that’s part ringside boxing announcer and part fashionista." Both of their episodes will premiere next year.

Osbourne said he was attracted to the role because of his 2-year-old granddaughter Pearl. "The whole reason I did the show was for Pearl," said the man who was once arrested for urinating on an Alamo memorial while wearing his wife's dress. "She has Nick Jr. on 24/7. I can’t wait to see her reaction when she hears my voice come from Sid Fishy’s mouth."

Osbourne may be able to draw on past aquatic life experiences when creating the character of Sid Fishy. Tony Iommi, Osbourne's Black Sabbath bandmate, revealed that Ozzy once "haul[ed] a shark through a window, dismember[ed] it and soak[ed] our room in blood."
