Mumei and the others are thrilled with a sudden pool day. However, their joy turns to horror when shadowy figures appear in the water. Sharks with plans of world domination? How can this be? With no possible escape, how will Mumei and the others cheat their way out of this new challenging test?
I will be the one to judge whether or not you 
humans are worthy of existing on this planet.
سأكون من يحكم على أحقيّتكم أيّها البشر
بالوجود على هذا الكوكب أم لا
Ich werde darüber urteilen, ob ihr Menschen
es wert seid, auf dieser Erde zu existieren.
Yo juzgaré si los humanos
merecen existir en este planeta.
Yo juzgaré si los humanos
merecen existir en este planeta.
Vous, misérables humains, devez mériter
le droit de fouler cette terre !
Sarò io a giudicare se siete degni o meno
 di esistere su questo pianeta!
Estou dizendo que eu julgarei se os seres 
humanos merecem ou não existir neste planeta.
