Finally, construction on the secret hideout begins! When Serufu invites Purin to build it with them, Purin’s secret is revealed. Together, the club members work through rainy days and sunny ones while their summer vacation deadline draws nearer.
And all the school buses 
left a long time ago!
!كما أنّ حافلات المدرسة قد غادرت كلّها
Oh nein, und der letzte Schulbus
ist auch schon längst gefahren!
¡Y a esta hora
ya no pasan autobuses!
¡Y a esta hora
ya no pasan autobuses!
Zut, j’ai raté le car scolaire !
E non ci sono più bus per tornare!
E todos os ônibus escolares
saíram há muito tempo!
А школьные автобусы
уже давно не ходят!
