In Monster Hunter Freedom Unite, the 2* Elder Quest to hunt a Bulldrome. I have better luck getting them from carves (in short, kill the thing) than I do from the quest rewards for capturing.

I suggest stocking up on 'em too. Quite useful, and Bulldrome parts can be used to make some cheap and easy health increasing decorations.
