It's Summer, It's Pool, Let's Go! (JP: なつだ！プールだ！レッツゴー！Natsuda! Pūruda! Rettsugō!, CH: 夏天到！奔向游泳池！Xià Tiān Dào! Bēn Xiàng Yóu Yǒng Chí!) is the Third-Fifth Collection/2007 Spring-Summer song of Seaside Stage. In the Third - Fifth Collection ROM, it is referred as B025.
So have you seen a swimming pool dry,
Strangest kind of feeling,
Let me tell you kind of what it looks like, it's a great big box with funny walls,
The bottoms kind of dirty you see,
The grass grows out from cracks on both sides,
Empty pool without someone to play with, that's when something happened to me,
I, have a secret that a pool, shared,
with me and I want to tell you as I think I heard it,
Clean up, clean up, scrub and scrub and what we do then,
Summer fill it up, with the water again,
Thank you for sharing your secret and your wisdom with me,
And when summer comes around, take care of me too.
