School is starting tomorrow, so Ashibe-kun calls his friends together to do lots of playing while they still can. He's even worked out a very detailed play schedule for them all to follow. They work their way through the list, but after a while, they start to grow tired of the whole thing. This isn't even "playing" anymore!
I'm making a river in this mountain tunnel!
!سأصنع نهراً في هذا النفق الجبلي
Aus diesem Bergtunnel kommt ein Fluss!
Hagamos una montaña, 
un túnel y un río.
Hagamos una montaña, un túnel y un río.
Sto facendo un fiume
in questo tunnel nella montagna!
Это будет тоннель для речки!
