Things like Dragon Cave and Pokefarm I just call clickies, myself, since they require clicks/views to grow. Breedable/Changing pets are more like, as jellysundae said, art that someone draws. They typically have a set time in which they will grow to the next stage. *nod* Just really requires ability to use templates, edit, color, and certing the pet.

Again thank you all for the warm welcomes 8D
