Sinktember - Monster Girl 25

Monster girl. Hell yeah, I adore this promp. I'm sure everyone will be very creative about it and not draw just mermaids.. I'm very sure.

As Lily was diving at the sunked part of Agatha's castle, she find the one and only owner of the castle in peril! Without her broom and airless! Lily quickly swim close to her and is now trying to lead her to somewhere to breath....

It would be a shame if her amulet power run out, right?
