The principal adores his grandson very much and asks the Sket-dan to prepare a picture play to entertain him. They decide to base the story off of Momotaro, but change things up from the usual... Afterwards, he asks them to play with his grandson for an afternoon, but the kid doesn't seem interested in having fun at all.
I bet he wants us to play with 
his grandkid directly this time.
Aposto que ele vai pedir para a gente
 brincar direto com o neto dele agora.
