Dog ate muffin cups... Do you think he will have a blockage?

My dog ate 4 muffin cups and I'm worried he might get a blockage. He's had a blockage before from eating a rope bone, but that was a long time ago... I have nightmares of Grey's Anatomy where the guy ate his book and needed it to be surgically removed. I realize that was a show and this is a whole other mammal, but... I worry about him and it's a lot of paper for a little 30 lb guy...
