That's awesome. I probably saw 4 or 5 episodes of Yo Gabba Gabba this weekend hanging out with my family (my sister had a baby a couple months ago). That show's a trip. I'll have to look out for this one.
I love this show. My brother is 2 so I end up watching quite a bit of it. Rivers is awesomely goofy, so I think he's perfect for the show. It's too bad it'll be so long until it comes out.
