The three girls have trouble accepting their circumstances, but they're immediately given an unexpected assignment...!
I left my shoes on the bridge!
!تركتُ حذائي في الجسر
Ich habe meine Schuhe
an der Brücke vergessen!
¡Dejé mis zapatos en el puente!
¡Dejé mis zapatos en el puente!
Ho lasciato le scarpe sul ponte!
Eu deixei meus sapatos na ponte!
