Seriously. Have you seen it?
While you're at it, you may want other polymorph spells to round out your collection. I made a pig and turtle guide in 2007, and the Black Cat is 2k gold if exalted with the Kirin Tor.
I made a polymorph macro for my character, settling on a simple one after tinkering with focuses:
The result is that my polymorph button shows the rabbit face (because it's awesome) and chooses a random poly to use.
#showtooltip Polymorph(Rabbit)/castrandom Polymorph(Rank 4),Polymorph(Rabbit),Polymorph(Black Cat),Polymorph(Pig)/emote turns %t into something delicious.
I also auto-emote "[Character] turns [target] into something delicious." This is because she's a Draenei who will become a Worgen when I'm able to race change her, and I think a Worgen would like to eat all of the available polymorphs. Don't you?
