Your mission

Biscuit the bear baked a special cake and locked it in a box. He says opening it will be "a piece of cake". He does not mean a slice of cake. He means it will be easy! A saying like that is called an idiom. Its real meaning is different from what the words say. Nobody is going to tell you what these idioms mean. Use the stories around them, and help each other.
