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?
Stop ogling me or I'll smash you, 
you knotweed bug!
كفّ عن رمقي بهذه النظرات
!وإلّا سحقتك يا حشرة البطباط
Beglotz mich weiter so notgeil
und ich zerquetsch dich Knöterich!
¡Te aplastaré si me miras así, insecto!
¡Te aplastaré como
me mires así, insecto!
Si tu me reluques encore,
je t’explose !
Guardami con quegli occhi sudici
 e ti riduco in poltiglia, parassita!
Não olhe para mim com esse olhar vulgar,
 ou vou te esmagar como um inseto!
