Monsters in the City

Professor Proof has invented an incredible machine with which he wants to prove, among other things, that the traffic lights and clocks in Lübeck are not controlled by us humans. From whom then? Apparently you don't know them yet, the tiktok and traffic light trolls in our city! Or the blubs, gurps and last but not least the sand shark? Only monster experts manage to lure the small, funny creatures out of their hiding places. Are you and your team exactly one of these experts? Very good, because Professor Proof has had a little mishap and he urgently needs your help.
