Every expansion pack has its own issues during the development process. Odd things can happen when things don't work as they should, and for the Pets PC expansion pack that was no different. Late last year Maxis already revealed a few bloopers on the official site, and recently they've added two more pictures. You can see some big heads and a strange family tree, but there's also a short video showing some real good shoveling. Go to the bloopers page to see them all, including the previous Pets bloopers.
