Tongue Tied, the intriguing debut iPhone title from Mojo Bones, will be released on December 15th.

In this physics-platformer, you play as Mick and Ralph, a pair of unfortunate pooches who find themselves in an unusual predicament.

Yes, they're tongue tied.

That is to say, they have been tied together by their long elasticated tongues.

Your task, then, is to guide these canine chums through 50 challenging levels - in search of the 'Wonderbone' - by stretching and firing them at the most appropriate moments.

Game Center support, a variety of unlockables, and tons of perilous obstacles combine to form quite the comprehensive package.

Tongue Tied will be available from the App Store this Thursday (15th December) on iPhone for $1.99.
