Their creator jissai1988 is a vain, vain bastard and the more attention, praise, and general positive feedback he gets, the more inclined he is to make other Shimeji (I know for a fact Gwen and Gwaine are already in the works. Gwen is not amused by Gwaine's drinking.)
So, anything positive to say about the Arthur and Merlin shimeji? Any cute pictures, fun moments, ect to share? Any funny screenshots?
Basically, if you're having fun with them, tell us, show us, or otherwise share with everyone! Your own screenshots or others, then come share in the cuteness!
That last link leads back to this post, so if you repost this it'll lead back here with minimum fuss. :)
