麥兜是一只右眼上有個胎記的小豬。他有一顆金子般的心，但他不是很聰明，什么方面都平平無奇；盡管如此，他也有自己的夢想。每一次他嘗試著達成自己的理想，他都會失??；他會感到失望，但依舊進取，追逐著自己其它的夢。他就是這樣創(chuàng)造了自己的一片天地。他單純而簡單的生活，以及雖不完美，卻積極向上的生活態(tài)度，和永不放棄的精神，使得他受到了大眾的歡迎。
The name McDull actually has a story itself. When Mrs Mak was going to give birth to McDull, she saw a magical plastic basin （pronounced roughly as “dull” in Cantonese） flying over her head. Immediately, she made a wish for her son and hoped he could be smart、good fate and sharp. After the wish, the basin dropped to the floor. Believing it a sign from the gods, she named her son as “Dull”， although it is a little weird.
麥兜名字的由來有一個故事。麥太臨盆去醫(yī)院準備生麥兜的時候，她看到了一只神奇的塑料盆（粵語中叫做“膠兜”）從她頭頂飛過。由此她向塑料盆許了一系列的愿望，希望將來的兒子能很聰明、長得帥，還有運氣要好，最后塑料盆終于落地。麥太認為這是老天爺傳遞的異象，于是取名麥兜，雖然聽起來有點奇怪。
