Bowie stars in SpongeBob

David Bowie has voiced a character for cult children's cartoon TV series 'SpongeBob SquarePants'.

The rock star lends his voice to a character called Lord Royal Highness for an episode of the sea bed-set series to be shown next year. "At last. I've hit the Holy Grail of animation gigs," the 59-year-old wrote on his website.
