It's the artwork for the "Shock Blow" Attack Action card from Ep.3. After trying to imagine this being one of all the monsters from every episodes, what is that O.o; ?
That with the unobtainable Toy Rappy card, if this monster does not appear in Ep. 1, 2 or even 4, is that a sign for another episode? I'd say unlikely, though.
...why the heck don't the IMG and URL BBCode work O.o; ??? I can't either post the image or even make a hyperlink.
