Goma-chan is fascinated by footage of the Snow Festival on TV. He must really want to see snow! But there's no snow in Tokyo right now... So Sugao-kun brings up the idea of making it snow for Goma-chan! Yuma-kun, Mao-chan, Yumiko-chan, and the Sakata brothers all join in to set up a Snow Festival just for Goma-chan!
There's no such thing as 
snow that doesn't melt.
لا يوجد ثلجٌ لا يذوب
Es gibt keinen Schnee, der nicht schmilzt.
Ça existe pas,
la neige qui fond pas.
Non esiste la neve che non si scioglie.
Если не тает, значит, не снег.
