Let's make: hydra! (Patreon)

Haven't done one of these in a while! For those not familiar with this kind of games, it works based on comment order here on Patreon.

In this case:

First person to comment decides integument type. 

Second person to comment decides shape of first head  (can be an extinct, extant or mythological animal species). 

Third person decides horn shape or some other detail of the first head (ears? fangs? whiskers? go wild) . 

Fourth person decides shape of second head. 

and so on...
