Rubber Octopus Dog Toy

I need a 3D model for a dog toy. It will also be used for production mold. Please take a look at the attached for an concept example. You can be creative and change it if you like. This will be a dog chew toy and should have a lot of texture as well. There should also be room in the body of the octopus so 4 layers of rope will fit through. Model should be approximately 8' tall and fit a 1" rope through it.
