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?
Dim-witted fools who cast 
aside our Mother Ocean,
المغفّلون الذي يهجرون محيطنا الأم
Ihr einfältige Rasse, die Mutter
Meer den Rücken zuwandte,
Idiotas que abandonaron el gran océano,
Idiotas que abandonasteis
el gran océano,
Vous qui avez abandonné
notre mère, l’océan,
Voi, idioti che ignorate la nostra Madre Oceano
Fizeram a burrice de
 abandonar a Mãe Oceano...
