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.
They're hard as a rock!
!إنها قاسية كالصخرة
Die sind steinhart!
¡Son como piedras!
¡Los míos también lo son!
¡Son como piedras!
¡Los míos también lo son!
Sembrano fatti di marmo!
Nossa! Que duro!
Твёрдые, как камень!
