Bob the Crayfish is a very likeable character. When one has big claws for appendages it only seems right to make the most of this opportunity. That he does and has much fun in the process.
The inspiration for Bob The Crayfish came after Gary had created a series of characters for RiverSmart Australia. The characters were a simple, clean design. This simple design inspired Gary to introduce a new character in the Swamp in that same style.
