The next sentence: ¿Hay un autobús turístico de la ciudad? This means the open-top buses that take you around the city while you get information.
At the bus stop someone advises against it: today is the day the locals throw eggs – “Eier” – at that bus (hay un autobús). The tourists inside are holding a hedgehog (“Igel”) and want to cook it, “kochen” (turístico) – at least they are thinking about it out loud, “laut” (de la). At the back of the bus sits a singing judo fighter eating dates, “Datteln” (ciudad).
