What is that Department 56 collection of christmas characters made of gl bubble/ball shapes?

I found them in TJ Maxx last season and fell in love with them, and am wondering what the collection is and where or if I can even find any more because I absolutely love them! They also bobble at some point. The bigger figurines bobble at their heads, while the smaller ones or the ornaments usually bobble at their heads and/or their limbs. I would so appreciate the help. Thank you!
