What's your favorite Littlest Pet Shop cartoon series?

My personal favorite is the 2012 LPS. And since I watched at least one episode from all of them, here's how I rank them from best to worst:

1. Littlest Pet Shop (2012)

2. Littlest Pet Shop: A World of Our Own

3. Littlest Pet Shop (1995)

4. Littlest Pet Shop Presents
