Well Dawn, I'll just as'sume that you came back from either V1 or V2. Well for one, the prices of pets has risen since then, especially the retired CS Creatu such as the Omni, Kioka and Liyure.
In V3, the Enchanted Springs, located on Atquati, has been put to good use as you have the change of getting a new Creatu egg, the Quelis, after taking a dip in the Springs for 16 consecutive days.
If you have any other queries, feel free to rmail me. =)
