Serval: Imperial! :D Male Imperials are my favorite. I'm hoping to have one some day.
And he's very pretty. And that's a... Navy primary? It doesn't look so bad with the Clown gene and the Seafoam secondary. Navy's kind of one of those iffy colors that looks better on some dragon types than others.
Punk: Lol. Congrats on that four-egg nests with the Pearlie. :3 And those babies are cuties! I think I like the Ice/Coral the best, mostly because I'm not a big fan of of platinum. XD But they are all pretty.

And if anything, you could level up the dragons you want gone a few levels and then exalt them and get an okay amount of treasure.
