Ask SillyThings to give you something to do and it will give you something funny to act out.
For example, "Act like a mokey", "Act like you just ate a really sour lemon", "Do your most silly dance", "Act like you are standing on hot lava", and many more.
You can take turns asking SillyThings for something to do or, like our family prefers, randomly ask for something in order to bring some smiles to the room.
