"Brumilla and the Horror Festival" is a short story that appeared in the double booklet magazine Süddeutsche Zeitung Familie, a magazine for both parents and children. It speaks of a teenage witch who is allergic to frogs and that's a big problem for her. She needs to drink an invisibility potion to go to a Horror Festival where she would otherwise be in great danger. Being that the secret ingredient to the invisibility potion is frog saliva she is in a bit of a jam. She gets an out of the box idea and tries to replace the ingredient with cat saliva. She brews the potion with her mom and gives it a try. The unexpected result is that instead of becoming invisible she becomes...a big scary monster...and that's all right as well.
