It's the day of the WUG Fan Club bus tour. Since Minami's stuck at work, the remaining six members do their best to entertain their fans.
While on the tour, Ayumi accidentally ends up inside a WUG animal costume and is taken to the hot springs by a confused Mayu...
But if I don't wash this, 
it'll mean trouble for WUG.
Si no lo lavo, les causaré problemas.
Si no lo lavo, les causaré problemas.
Si je ne lave pas ça vite,
les WUG vont avoir des ennuis.
Però, se non lo laviamo,
le WUG saranno nei pasticci.
Se eu não lavar, vai ser ruim pro WUG.
