Here are some download links for Shimeji~!
But please, try to use Google? He doesn't bite. And sheesh. Fine. No jokes. =3=
BUT REALLY. Before you er...cry about a shimeji because It's not listed, please don't cry about it. IMAGINE HOW MANY CHARACTERS ARE THERE IN THE ANIME WORLD THAT GOT SHIMEJI-IZED.
Maybe the character you asked is not yet released/made.
