The mystery of who stole a 44-pound gold cookie from the outside of the German headquarters of biscuit maker Bahlsen has been solved. Well, sort of.

A thief calling his or herself the "Krümel Monster" (Cookie Monster) has taken responsibility for the high-profile heist. And to prove they're in possession of the famous gold piece, the theif/hero posted a picture of themselves dressed as the iconic Sesame Street character and taking a bite out of their giant cookie plunder.

The photo also included a ransom note. Here is the English translation:

"I have the biscuit! You want it and therefore you want on one day in February, to give biscuits to all the children in Bult hospital. But those with milk chocolate, not those with dark chocolate and not those without chocolate. And a golden biscuit for the child cancer ward."

The note adds that if these demands aren't met, the golden cookie will end up "with Oscar the Grouch." (In the trash.)

This might seem like a good opportunity for Bahslen to do a little low-cost charity work and get back their cherished symbol. But at this point the company is taking the line that they don't negotiate with kidnappers -- even those who are just thinking of the children.
