The pet coloror!

A craftable item that changes the color of your pet. it would be crafted like this:

I=Iron ingot   W= water bucket i= iron nugget C=cauldron

     ICI

     iWi

      III               If you add a dye to this block, a window on it would show that color. You could put a pet in it, and power the block with redstone. Your pet would change to the color on the window, witch would then turn empty. To change your pet back to the default, put it in an empty-window pet coloror. This would all be super cool if it was in minecraft.
