If you give a mouse a cookie, he'll want milk to go with it. If you give him milk, he'll need a straw. When he's done, he'll want to see if he has a milk mustache.
You'll take him to the bathroom and he'll look in the mirror. When he looks in the mirror he'll realize his hair needs a trim. When he cuts his hair...
He'll notice he needs a broom. Once he sweeps, he might even wash the floors!
When he's done he'll probably want to take a nap. He'll crawl up, make himself comfortable and fluff the pillow. He'll probably ask you to read him a story.
You'll read him a story, he'll see the pictures and get so excited he'll want to draw! He'll sign his name and he'll want you to hang his drawing on the fridge. Looking at the fridge will remind him that... he's thirsty!
Once he's thirsty, he will want a glass of milk. Chances are if he wants a glass of milk, he'll want a cookie to go with it.
