I thought Hydrus revert to Common when pounded?

It does. Any pet that is Hydrus and ... a Bumbuss will revert to common -Bumbuss to Common Kumos. Transferring from user to user will keep the color/

That's why I wanted to check to see if anyone wanted an already hydrused pet before I pounded him and he got reverted to common. I grabbed him as something else I can't even remember and did the quest myself for the achievements.

I've got two pet names that I've been trying to figure out what to do with (Hoist and Haul) and I think Charter might fit well with their current concept. However, I haven't given it a whole lot of thought and I'm really not ready to do so at this time. (I am trying very hard to remain focused on my older concepts until I've got them at least reasonably represented before I move on to anything else.) I don't know how everything will work out but if you are okay with my uncertainty, I'd like to have the opportunity to have him around while I think about it at least. If my plans fall through, I'll certainly try to find him a good home.

Please let me know, yes or no. Thanks! :)

Sure. Sending friend request.

Thank you for letting me adopt him!

No problem! Please enjoy him.
