Goblin and "Yuki Usagi" (Snow Hare)

A goblin boy's father returns home with a red handball he found near the house of a girl named Yuki Usagi, prompting the boy to return it to her. The next morning, he sets out to find Yuki and arrives at a village where he sees children singing together. He finds Yuki sitting alone on her veranda, and upon introducing herself, she reveals she's been searching for the ball, which was a gift from her ailing mother. The goblin boy's actions lead to a new friendship with Yuki.
