McDull is a male pig who can be distinguished by a birthmark on his right eye. He has a heart of gold, but he isn't very smart and ordinary in every way; nevertheless, he has many dreams. However, every time he tries, he fails; he is disappointed, but tries again, exploring other dreams. In this way he creates his own colourful world. He lives his life simply and naturally. He is not perfect, but his attitude towards life, namely of never giving up, makes him a popular character。

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. Believing it a sign from the gods, she named her son as "Dull"。

大爱麦兜！！不知道有没有T友和我一样喜欢麦兜啊~~想当年我和同学张嘴闭嘴“鸡包纸、纸包鸡”“马尔代夫……椰林树影，水清沙幼……”，不亦乐乎~~最近新的麦兜又要上演了呢~~我的小心脏美滋滋的~~那阵我弟弟妹妹、同学、秦苏珊英语的好朋友过生日，我几乎都送画着麦兜的东西，到最后我同学都无奈了，哈哈~~他为什么叫麦兜呢？相信看过动画的人都知道，但是可能也有的人没看过，为了让麦兜被更多人知道，我给大家介绍一下~~下面还有找来的英文哟！

麦兜是一只右眼上有个胎记的小猪。傻乎乎的，过着平凡而又温暖的小生活。每一次他尝试着达成自己的理想，都会失败；他会感到失望，但依旧进取，追逐着自己其它的梦。生活十分单纯，虽不完美，却积极向上的生活态度和永不放弃的精神，就像一只小蜗牛，爬的虽然慢，但是却一点一点的爬，冲着自己的小幸福努力~
麦兜名字的由来有一个故事。麦太临盆去医院准备生麦兜的时候，她看到了一只神奇的塑料盆(粤语中叫做“胶兜”)从她头顶飞过。由此她向塑料盆许了一系列的愿望，希望将来的儿子能很聪明、读书好，长得帅，像梁朝伟或者周润发，还有运气要好，最后塑料盆终于落地。麦太认为这是老天爷传递的异象，而麦胶这个名字不好听，于是决定取名麦兜。
麦太也是很可爱的，哈哈
