Partyplankton: Dear Hedwig, if you could transfigure into any other type of magical creature for a day, what would it be and why?

Hedwig: (SarcasticStroppySnowy) I wasn't expecting anyone to ask me that, thank goodness you didn't say something embarassing about Magnus! I do love being a beautiful snowy owl, but if Magnus didn't mind, and it wasn't painful, I would be a unicorn, white and pretty like me. Harry would not get me to send mail to that Sirius guy all the time and and I 'd know what it feels like to have four legs that run fast on the ground. Also, of course, I'd have great fun poking Salazar and Draco with my sharp horn-giving them what they deserve! :P
