We're going to find 
who threw out their trash.
سنعثرُ على الشخص الذي رمى قمامته
Wir finden den Schuldigen,
der den Müll abgeladen hat.
Atrapemos al que tiró la basura.
On va trouver celui qui a fait ça.
Troveremo chi ha buttato l'immondizia nel cortile!
Vamos achar o meliante
 que jogou o lixo lá.
