Finned adds extra fins and wing fingers, increasing the overall flappiness by at least 10%.

While not free to edit, Finned can be redrawn or edited with an item or a Covering mutation. Please check the bottom of the section for pointers and ranges!

Custom Finned should include at least one extra fin on the body or finger on one wing. It can create fins in the Maximum range, and can edit new wing fingers (up to three per wing) originating from the Extended range. Finned on the body shouldn't cover more than about half of the body area. 

Individual fins can be about as large as the maximum size for Crested, being about as long as the width of the part of the dergon they originate from.  Their shape may mimic official lines, or may be drawn in other shapes, such as resembling fish fins.

Frilled adds long, thick fins to the ends of wings and points on the body.

While not free to edit, Frilled can be redrawn or edited with an item or a Covering mutation. Please check the bottom of the section for pointers and ranges!

Frilled's influence should come from eels, frilled sharks, and other creatures with thick fins with little visible ribbing. Frilled can affect the wings and any additional fins such as Crested, as well as adding new fins in the Maximum range. Similarly to Finned, it may add up to three new wing fingers per wing originating from the Extended range. Frilled may cover the wing finger claws and wing thumbs, and may introduce new claws near the ends of its fins.

Individual fins can stretch as long as the maximum size for Whisker, though they should not obscure more than 40% of the overall import.
