This sadly looking rabbit is named Mesousa - he has a serious case of depression (Prozac anyone?) and comes from the Japanese series Pani Poni Dash! (ぱにぽにだっしゅ!), which focuses on parodies, satires, and comedy with regards to both Japanese and American pop-culture (internet, anime, gaming). The story centers around "Becky", an 11 year-old child prodigy / mathematics teacher and the antics of her class. Mesousa is Becky's companion and is there primarily as a sacrificial victim to the series' slapstick comedy. The series started out as a manga and later on as anime, it was published by Square Enix and created by Hekiru Hikawa. Free download for this simple paper model is available below.
