This bunch of pics was used by urin and ZUN to make an april's fool announcement about a Kishinjou (Double Dealing Character) anime (that in fact, will never exist). I'm not sure how many fell for it, but i feel ashamed that i actually screamed of joy when i saw it.
ZUN yu do dis to me.

However, this pic here still makes me smile. I love Waggysaggy portrayed like this.

I'm pretty sure ZUN's said before that he has zero plans for an official anime because he believes it would marginalize the games, so anyone who thought he'd changed his mind was very silly.
