Re JCMidore: I did find some good matches, but I also say if you're happy with your Red Drugal, it works just as well as anything I found.
The Xweetok works with most any Pirate petpet, but I pulled out the Babaa, Eizzil, and Gangee because of their eyes. Note how similar they are to the Xweetok's. Also the Babaa has the dark color wool that matches the dark color stripe of the Xweetok. The Gruslen is there because he matches well not only in color, but in form (paws, tail, nose, ears, even the peg's on the same leg) and pose.
Similar scowls, and either red or black works.
And these are just miscellaneous color matches that may be a bit cheaper than having to paint a petpet. Then again, haven't checked the Biyako or the Seti lately... =\
EDIT: Petpetpets:
There's also one called an Aboogala that would look great, but I can't even find any on the trading post. Don't even know what the link to the picture is!
Re kcharles: The Brown Wocky was surprisingly hard for me to match; there's very few petpets with both those shades of brown. So most of what I've got here are approximate color matches, and some of them I picked out for matching poses or forms. Out of all these, I'd have to say my favorites are the Brown Faellie, the unpainted Khnum, and the unpainted Vacana.
Again, not an exact color brown. Just food for thought.
Re Labyrinth: Hope I found some pets that'll work for you, though I honestly couldn't resist throwing a few girly ones in there. The Royalgirl Kyrii just looks so great with a Faerie Drugal!
Beauty and the Beast?
It could work with either the Royalboy (left) or Royalgirl Shoyrus.
