Look to see if you can get to 79 without your blues. Then use your blues to make Titans, Fire for less shards, Moss for more shards, both I believe give the same xp.
145 tortoises, 3k terrorbird, 1503 fruit bat, 299 cobra, 1165 granite lobsters. puts you at 77 without your blues and saves you some reds for if u want to gather talon charms.
^the above amounts might be slightly off if you have more xp than the official highscores are showing atm. and should be rather cheap compared to some uses for them.
