Case-Mate (http://www.case-mate.com) has introduced its new Creatures collection of iPhone 4 cases that are “inspired by cartoon art and childhood fun.”

Monsta and Waddler are the first cases in the Creatures collection. The former retails at approximately US$29 and is available in green, pink, white and grey. Waddler also retails at $29 and is available in black, blue and brown.
 
From mid-April, the Monsta (pictured) and Waddler cases will be available from stand Q8 at the Gadget Show Live, online at http://www.bmcdigital.co.uk, http://www.cleverkit.com and at many retailers. In the coming months, new creatures will be added to the collection.
