Looking for an Ox Pet

Abba San

Legacy of Elijah [LoE] - Proud Grandfather
Now that the festival is over:

It was so cool to see all the people - especially non-aliance people - cramming into district 77 to celebrate the festival.

I used hundreds of Lunar tokens and ended up with hundreds of fireworks and libations. No ox pet. Anyone have an extra ox to sell - or trade for fireworks? Or, do you know where in Guild Wars I can go to dump the fireworks and pick up an ox pet?
