The members of Pandemonium are not getting enough exercise, so they decide to build a gym, but when it comes time for the opening ceremony, Beelzebub and the others find themselves staring at a Japanese-style bath instead. Since the facility already exists, they might as well get in… Later on, Beelzebub learns more about Mullin and the pet he keeps at home.
If I used some tricks to spy on 
them, then it wouldn't be fun!
إذا استخدمتُ خدعاً للتجسّس عليهن، فلن
يكون ذلك ممتعاً
Wenn ich sie mit Tricks begaffen würde,
dann würde es keinen Spaß machen!
¡Un truco para espiar
no sería divertido!
¡Un truco para espiar
no sería divertido!

Se usassi dei trucchetti per spiarle, 
non ci sarebbe gusto!
Não há aventura se trapacear!
Жульничество портит всё веселье!
