In German the following is a completely valid sentence:
Wenn hinter Fliegen Fliegen fliegen, fliegen Fliegen Fliegen nach.
Which translates to when flies fly behind flies, then flies follow flies. The same works for seals:
Wenn hinter Robben Robben Robben, robben Robben Robben nach.
My friend does not get what the music in the bottom is supposed to be. They played it on the piano but don’t recognise it. Can you help them?
