Penguingender is a xenogender used by those who strongly identify with penguins, or those who want to incorporate them into their gender. It is intended for use by autistic people, and can be a kingender or a delusogender, but doesn't have to be. Penguingender is associated with the feelings of feathers, coldness/dampness, beaks and webbed feet. It's highly inspired by ottergender.
