Can anyone tell me what the Rieklings are worshiping in Frossel?

It looks to be a model of a reindeer attached to a cart, so my immediate thought was Santa. I'm fairly sure that isn't what it's supposed to be though.
The back of the cart seems to have some sort of writing on it but i have no idea what it says.

Does anyone else who's seen it have any idea?

No idea. I just think it is an easter egg. One of my favorites so far.

Yeah, same. I love how detailed the reindeer is, even down to it's little pile of charcoal poo.

Yeah, i didn't notice to charcoal, nice touch. I just really enjoyed entering the room and seeing all the reiklings bowing down to it. It was a nice suprise.

Perfect line up for a Fus'Ro'Dah.
