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'm simply making sure you're 
not hiding any tools of evil!
أنا أحرص على عدم إخفائكم
لأيّ أدوات شرٍّ فقط
Wir sehen nur nach, ob ihr Gegenstände
mit habt, die ihr nicht haben solltet.
¡Me aseguro que no oculten cosas malas!
¡Me aseguro de que no ocultéis nada!
C’est juste un contrôle
pour détecter les objets pour tricher !
Sto solo controllando
che non abbiate strumenti sospetti!
Estou apenas verificando se vocês 
não estão escondendo nada suspeito.
