Saku and Yukichi receive invitations to Yume's birthday party. Yukichi convinces Saku that it'll be completely fine to attend since it'll be a costume party. However, will Saku and Yukichi really be able to fool all the parents and children there?!
I heard about Yuki-san from Yume. 
He's really quite a large cat.
Yume hat es mir schon erzählt,
aber Yuki-san ist wirklich ein großer Kater.
Yume ya me lo contó,
Yume ya me lo contó,
Yume m’avait déjà parlé de Yuki,

A Yume me falou do Yuki.
Ele é um gato bem grande mesmo, né?
Юмэ рассказывала мне про Юки.
Он и правда очень большой кот.
