Stage 1: Eggy
The egg has just been layed, and it basically just sits there like a lump for a while. If you don't RP your Genericus it won't hatch for a week. If you do RP, then I will probably hatch it faster. ^^ Up to you. This stage is androgynous. Lasts a week. Or less, if you RP.
Stage 2: Bebeh
Congratulations! Your Genericus hatched! Now you have a devious little furball to deal with along with the rest of your life. Haha, sucks for you. =P Anyways, this is when your Genericus comes into it's powers. Check the other post for those. They have minimal control, and not a lot of strength. Basically they just play around with each other, playing pranks on the adults. This stage is androgynous, as well. Lasts a week.
Stage 3: Kiddie
They are now old enough to go on quests! They are slightly more proficient in their magical-ness, but going on a quest would totally help them out with that. They'd be, like, uber-powerful. =O This is also the stage that their hormones kick in. That's right, love is in the air! That's about it. Finally you will be able to tell if your Genericus is a girl or a boy! Yay! Lasts a week.
Stage 4: Adult(erer) <.<;
Ohwow, your Genericus managed to pass the test of Adulthood. Coolness. They can breed, have eggies, and all that cool shtuff. You can do quests in this stage too. In fact, that's the only way that your Genericus's magic level will be changed. They don't grow anymore (unless Zy wants to 'discover' a new stage. =P) Um? yeah? Lasts forever.
