Pretty sure an old, outdated manual isn't exactly canon
yes it is
dumblrinas always trying to make EVERYONE trans or gay
just ignore it, this isn't canon
this post gave me river nile disease
I'm pretty sure it's a joke anyway
you see that's actually what worries me, because he did say it in the 90's
early instruction manuals also say birdo is a dude and vivian is a crossdresser
things change
....
it's still canon that birdo's a dude
