Males have unlimited breeds each season while females only get one. In order to breed, you need both Sphixy scales and either a One Charm Bracelet, Two Charm bracelet, or Chain Necklace. A list of items you own can be found on the website in the Breeding Section. Eggs take seven days to be delivered by the Ethereals and three more to hatch. There is no fee to breed Chubby Dragons if you have the needed items. If you don't have the items and want to breed, it will cost 15k. It is expensive but it is compensation to the Ethereals for your lack of the items they need.
Aquitia's breed in exactly the same way except that they require only Sphixy Scales. Only chance will get you twins and breeding two males or two females is possible without forcing them together. The fee for breeding Aquitia is 30k in addition to the Sphixy Scales, as their offspring are very rare and valuable.
When they come out of the egg, Chubby Dragons grow so quickly from their small state, a picture of them as babies ha yet to be captured. However, an image of an Aquitia before it's growing has been captured. Therefore, Aquitia have three stages; egg, child, adult.
Aquitia and Chubbies may be bred to one another with a 25% chance of an Aquitia. Sphixy Scales are required in addition to a 40k fee.
In breeding Season, cosplays pass one small piece of clothing or hair to their direct offspring. Their grandchildren won't get anything though. Only direct descendants. To lighten Ambie's workload(cause she will end up shading them all >.<)cosplays only get one breed each season regardless of gender. They require the same items as normal Dragons though.
The markings are randomly determined by a roll of random.org. The baby is either normal, or one of the parent's markings. Breeding two Dragons of the same markings guarantees that marking on the baby.
