What is the difference between Emma & Penelope Rabbit? Or Lucy & Jeremy? Ella & Lewis?

Both Emma and Penelope are the same base animal. Their differences are in the outfits we've selected for them (for pre-dressed dolls) and the stories that they come with. For example, Emma is a big fan of May Day and practices May Day dances all year long while Penelope enjoys dressing up and craft-making. The same goes for Lewis and Ella Toad, as well as Jeremy and Lucy Owl.
