The shinobi receive a mysterious message delivered by arrow from an unknown, and potentially deadly, assailiant who lurks in the shadows. The letter lures them to an empty spa resort, where they'll begin a trial like they've never faced before. But first, it's time for everyone to have a squirt gun fight in skimpy swimsuits!
Once you're totally naked, you're out.
Sobald man ganz nackt ist, ist man raus.
Al estar desnudas, perderán.
Las que estén desnudas, perderán.
Être nue entraîne l’élimination,
Non appena si è completamente nude,
si viene eliminate.
Quem ficar totalmente
nua está eliminada.
Останетесь без
одежды — проиграли.
