He lends his voice to Lord Royal Highness

Who visits a pineapple under the sea? Da-vid Bo-wie.

The iconic singer-actor has voice a part on Nickelodeon's aquatic cartoon "SpongeBob SquarePants." Apparently, he mainly took the job because his daughter Alexandria is a fan of the show. Bowie blogged about his gig on his official website.

"It's happened. At last. I've hit the Holy Grail of animation gigs," he writes. "Yesterday I got to be a character on ... tan-tara ... 'SpongeBob SquarePants.' Oh Yeah!! We, the family, are thrilled. Nothing else need happen this year, well, this week anyway.

"My character in this special longform (I think a half hour special) show is called 'Lord Royal Highness.' Alrighteee!! It won't air unfortunately for another eight or nine months but then, watch out. Or at least watch."

There aren't any additional details about what Lord Royal Highness does on the show, how he likes his Krabby Patty cooked or whether or not he moonlights as an androgynous alien rock star called Squiddy Stardust or Ziggy Starfish.

Bowie received a lifetime achievement honor at the Grammys this year. Highlights of his acting career include "The Man Who Fell to Earth," "The Hunger," "The Last Temptation of Christ" and "Labyrinth." He next plays radio inventor Nikola Tesla in "The Prestige," which opens on Friday, Oct. 20.
