Do you guys remember this: viewtopic.php?f=4&t=4288#p21922
We've already seen what appears to be a snow world in the game, so it's no surprise that they've probably been working on it, especially as Grant has done music for an ice world already.
I'm surprised that Andy said Grant does not have the Toybox, which means it must be an early build of the actual game. I guess what he's really stresing here is that we're not going to see the Toybox imminently, so don't get our hopes up. Maybe I'm just being pessimistic!
