"Bob" Grandfather is a painter who lives with "Nian" and "Moin".
"Annie" Grandmother is regularly sponsoring the paintings of "Bob" Grandfather.
"Nian" and "Moin" were also able to eat delicious food.
But a few days ago, "Bob" was sick and lying down.
So he can not draw a picture.
“Annie” visits tomorrow, but the painting is not finished yet.
"Nian" and "Moin" will paint the ball and roll to complete the picture of "Bob" grandfather.
Will "Nian" and "Moin" be able to finish the picture well?
