How to party

“Let's party at your house,” duck said. 

“My house!” I said. 

“Good. I want to eat grass,” cow said. 

“We don't want to eat, we want to stay in the mud,” the twin piggies said. 

“Me too. I want to swim,” duck said. 

“Hence let's go to the lake,” I said. 

“Why?” All of them said. 

“Over there, there are grasses for cow to eat, water for duck to swim and at the shore of the lake there is cool mud for the piggies to stay,” I claimed.
