Runner Haven mentions "moon dolphins" anyone know where I can get stats or at least a description of these creatures?

Never heard of them.
Maybe they are awakened dolphins that looks like any dolphin at first but they actually "moons" the visitors...

When Drop Bears invade from the sea like the furry little vikings they are, they generally ride Moon Dolphins.

Let your imagination fly, man. Its what being a GM is all about.
For some reason I am reminded of an old fun Sega game.

Moon dolphins are all happy like virgin horses, right?

I'm so having a disturbing mental image right now...

There were references somewhere to mage dolphins that followed the moon? totem, in SR2 I think.

We have our own specially trained Drop Bears for that. They don't need fuzzy dolphins.

Yeah, but the dolphins make lugging all that cutlery so much easier.
