有一天，大笨狗灰灰到一条河里去游泳。他非常高兴，因为没有一个人。他不知道，河里有食人鱼。当他进入河中的时候，食人鱼也非常高兴，他们想这下可以饱餐一顿了。他们准备从他肥肥的屁股发起攻击，结果，当这群食人鱼靠近他屁股的时候，灰灰突然放了一个臭屁，他的屁确实太臭了，离他最近的食人鱼全部都臭晕了，其他的食人鱼都吓跑了。大笨狗真高兴，游泳之后，还抓了许多鱼。
第二天，大笨狗灰灰又去那条河里游泳。这次，食人鱼都学聪明了，都离他的屁股远远的。它们跑到他的前面，准备从他的头部向他发起攻击。碰巧，大笨狗昨天吃了太多食人鱼的肉，没有消化。就在水里打了个大饱嗝，由于他的牙齿好久没有刷了，那个饱嗝比他放的屁还臭，更多的食人鱼被臭晕过去。大笨狗又抓了许多鱼。
从此，大笨狗灰灰在这条河里游泳，没有食人鱼敢靠近他。
One day, the big fool dog HuiHui went swimming in a river. He was very happy because there was no one there. He didn't know that there were piranhas in the river. When he entered the river, the piranhas were also very happy, and they thought they could eat a meal. The results, when this group of piranhas near him, ready attack from his fat butt, HuiHui suddenly put a fart, his fart was too smelly, the nearest piranhas were all dizzy, the other piranhas were scared off. HuiHui was really happy, after swimming, also caught a lot of fish.
The second day, the big fool dog HuiHui went swimming in the river again. This time, the piranhas were all smart and far away from his butt. They run in front of him and were ready to attack him from his head. As it happens, HuiHui ate too much fish meat yesterday, and did not digest. In the water he made a big burp, because his teeth for a long time without brush, the burp was more smelly than his fart. The nearest piranhas were dizzy soon. The big fool dog caught a lot of fish again.
Since then, when the big fool dog Huihui goes swimming in the river, no piranha dare to approach him.
