Left to Right: Astral, Sparkle, Swimmer, Mineral, and Flamethrower from Karabear Comics Unlimited have turned up along with an alternate universe version of Ozma. Ozma identifies the monsters as Oz natives, the Growleywog being the giant hulking creature and the bodnage gear guy is a Whimsie.
I know someone that could give you a hand with the Growleywog and the Whimsies. Stefan and the Queen have appeared in the Caper, but where did William go off to? Hmm...
Now... the Whimsies gives me the willies! :|
