On her way to the park, Momo drops the precious bell her mother gave her. Meanwhile, Tama is bothered by the fact that Momo hasn't arrived yet, so he goes looking for her and hears the sound of Momo's bell coming from the drains...

Tama looks up at a sky where fluffy clouds float by as they always do. Where do clouds come from? Tora leads Tama and the others to the place clouds come from, and that place is...
In the sky, a cloud that 
looked just like Pochi
رأينا غيمة في السماء بدت كأنّها بوتشي
Wir haben am Himmel
eine Pochi-Wolke gesehen,
Vimos unas nubes como Pochi y Bull,
y la de Bull lo estaba persiguiendo.
Vimos unas nubes como Pochi y Bull,
y la de Bull lo estaba persiguiendo.
C'era una nuvola nel cielo
che assomigliava a Pochi
В небе за облачком, похожим на Поти,
гналось облачко, похожее на Булла.
