There are three stages for each gender.
Egg
All griffons start as an egg. The gender of the egg is unknown, but details about its pelt and feathers are given away by its coloring. This stage lasts one week.
Chicks -- new name?
Chicks are children. They do not know how to fly yet and are curious and interested about their surroundings! This stage lasts two weeks.
Gryphon
The adult stage. They can fly, mate, create flocks, and more.
Regular
The most common griffon available in the shop, they are often sociable creatures who love adventure and exploring. They live all over Crystal Mountain, and are very likely to flock together. They enjoy flying and are more likely to interact with humans who visit the mountain.They have no special powers.
Demonic
Rare griffons, they live in the dark, dangerous caves on Crystal Mountain. Not all are evil, but some are very wicked. They are not as likely to flock together with one another and are more likely to fight. They enjoy scaring regular griffon, and unfortunately some like to hunt/enslave them. Not all are like this, however. Some are just misguided and too mischievous for their own good.They are enemies of Angelic griffons. No special powers.
Angelic
Rare griffons, they live at the peaks of Crystal Mountains and sometimes in the clouds. They are enemies of Demonic griffons and often will have nothing to do with them. They are natural healers. They, like Demonics, do not flock together and are very unlikely to interact with human visitors as humans never make it to the peaks. They consider themselves protectors of the regular griffons, but some can be pretty high and mighty about their breed.
