顽皮小白貂

槌谷揺というごくごく一般的な男子大学生が、オコジョを飼うことになる。名前はなく、ただの「オコジョ」（愛称を付けて呼ぶ者もいる）。槌谷やオコジョの周りの人間・動物により色々とおかしい出来事が引き起こされるギャグアニメである。不条理な部分も多い。

アニメでも本編以外に学校を舞台とした「オコジョ番長」編やゴジラ映画のパロディのメカオコジョ登場編も放送された。

Haruka Tsuchiya is a plain and simple university student who has a pet by the name of Okojo-san. Okojo-san was actually born in one of the mountains in the North and brought to one of the pet shops to be sold. Determined to get out of the pet shop, Okojo-san formulated an escape strategy and ended up in the house of Haruka. There are always funny and strange occurances happening around the two, be it the people or animals who are near them. This is a gag anime in which absurdity is the main feature of the story.
