What's The Big Bang Theory's John Ross Bowie doing on Sofia the First? Sea-horsin' around!

On the first-ever Sofia the First primetime special The Floating Palace, Bowie will lend his voice to Sven the seahorse, part of the welcoming committee for Sofia (Ariel Winter), who is magically transformed into a mermaid.
