Yes, claymation!! we do need more of that on NG these days :)
The part where they jump looks a bit odd (but that's a hard thing for claymation anyway, it normally requires others tricks like a support or a cord that you can later erase from the pictures), but I liked the rolling movement a lot.
While the story felt a bit inconsistent, it was entertaining and it looks like it was fun to make. I still wish they could find some tacos on their journey.
