Seem this is what happens when you let the group chat shout out ideas and let the artist run wild! Pink high chair, pink diaper, strapped in so I can't escape (and won't slide out of the high chair as easily), mittens and bonnet, someone forcefully mushing my diaper seat... Slightly different from how I'd originally imagined it - and I ain't no girly sissy - but I rather, umh, like it!
Thanks to both the artist and the people who, ahem, "offered ideas"!
He also did a slightly less girly version afterwards.
