Weirdest thing you found in a prepacked item

Last week I saw someone open up a can of Dr. Pepper, only to find it was completely empty. No holes had been drilled into the can, so it wasn't a case of the liquid leaking out. It appeared that the can had not been filled at the bottling plant, and somehow got shipped out.
 
I found a weird piece of paper with some random numbers on it inside a box of cupcakes.
 
My copy of Sonic ‘06 from Ebay contains someone’s heartfelt confession about not liking their father under the manual.

Got a used copy of Animal Crossing Wild World from gamestop and the used save file, someone had sent erotic fanfiction to all of their villagers and put it on the town bulletin board.

Once found a live mole in a bag of sealed dog food.
 
Found an unidentified tumor looking thing in a can of Chef Boyardee in 2001.

Poked at it with a knife and never did get any conclusive data that could tell me what it was. Most likely part of a rodent but really who knows.
 
I bought a piggy bank from an op shop and when I got it home I realised something was rattling inside of it. Turned out to be a 1966 Australian fifty cent piece. They're notable because they were pulled out of circulation 1969, and also because they were 80% silver. They're an extremely common coin and they're not worth much on top of silver price, but it was an interesting little bonus for the casual collector.
