The hungry German man’s start to the day was completely ruined when he discovered the dead bat in his bowl of cereal at his home in Stuttgart.
He was left feeling more horrified than hungry when he realised the mummified mammal was not a Halloween themed toy.
The incident was reported to health officials who are attempting to establish how the errant bat managed to fly into the box of corn flakes.
They believe the bat may have flown into the plastic packaging by mistake and suffocated to death.
Scientists are investigating whether the bat had flown into the box of Mini-Zimties cereal at the factory or after they had been opened.
Food safety official Jorg Sturmer said: ‘I have never seen anything like it. This really is an unusual case.’
Last month, a live frog was found jumping around a Waitrose salad bag bought by a family in Hampshire.
