A cat with character, a cardboard box with a hole in it, and some drawing skill… so funny!
Here’s the story: the cat’s name is Guagua (“瓜瓜”) It was Guagua’s birthday celebration for which his owner, a user named toshiya86 from a Chinese blogging service Weibo (to see her page, unfortunately, you have to be registered in Weibo) drew these characters on cardboard. Characters and anime included: Christine Mi, Dino, Gold Sparkle, Kiki’s Delivery Service, QB, Green Drive, the Old Anchor, Gintama and Naruto.
