Hey Eroism you should add a dolphin enemy because thay are known to attack humans because of horny out of any reason so it would be perfekt for if you add extentions to the roadmap after you're done with the curent roadmap
Someone already suggested a dolphin enemy on the update thread :P.
It is a good idea, but given the issue with the CGs, execution will depend on having someone capable of making the animations for such an event. Without an animator it will be very difficult to add this encounter.
