I think it's time that you guys should add a new category on pets section where it will be called "Limited". These type of pets can only be obtainable by buying the egg for 1.7k+ platinums. These pets will serve as a collection to all collectors and these type of eggs shouldn't drop from egg zavier(this type of pet shouldn't affect the achievement needed on pet aps in short it's just for flex purpose LOL). The only way to get this type of pets is by Limited time sale or put this on egg vendor that is available during egg zavier event so that you'll be able to make a good amount of money since the event is only available for 2 weeks. (Please put an effort into designing these pets so that lots of supporters will buy it to support your game even more)

That's all.
