Banane-schoko-mandelsplitter
On a visit to the 
6 Heidelberg Christmas market, you should be able to purchase a
Banane-schoko-mandelsplitter from Crepe Guy - that's if he's not just out of
splitter. The problem is that they're usually alright on the banane, no problem
there, but the man who delivers their schoko, pancakes, mandelsplitter and so on, sometimes has little accidents. However, you usually get a letter from Crepe
Guy explaining the problem. For anyone not initiated, it's banana, chocolate, chopped nuts, in a pancake.
It is one of Steve, Mike and David's great regrets that they did not have time for a Banane-schoko-mandelsplitter during Mission 6.
