Momotaro is running excitedly indoors ＠Gorilla

Momotaro's been running with excitement all morning! His family follows him.　
What's going on? Momotaro is running excitedly indoors in the morning. The rest of his family (Genki, Gentaro and Kintaro) follows him, kind of chases him.
In the cold, snowy outdoors, baby Kintaro is frequently touching his feet, as if he is dealing with the spikes on them.
★ It's interesting to see mother Genki and baby Kintaro jumping from a high place to the ground at the same time!
