I posted this over on my blog, but I'm going to post it here as well since it's a more convenient viewing place.
For those interested in battling with these babies, here's a list of their abilities as seen on the PTR (build 16155). From lowest level ability to highest (2, 4, 10, 15, 20, 25):
Cinder Kitten -
Darkmoon Eye -
Darkmoon Glowfly -
Darkmoon Hatchling -
Imperial Moth -
Imperial Silkworm -
I think the Pandaren elemental spirits are still a work in progress since they all share the same exact 6 abilities in the same order: Water Jet, Frost Nova, Geyser, Ice Lance, Frost Shock, and Tidal Wave.
