We found a stained glass window in Aalesund, Norway.
It is three kings and if you look at them upside down they look like three cat trolls.
In 1904 Professor Jervel worked out a spell to release the trolls, when the trolls came to life they burnt down the town. Some people said the trolls faces were in the flames.
He made a spell to trap the trolls in the new buildings of the town.
So he put three cat trolls in a window so it looked upside down so the bad wizard couldn’t see them to release them.
