How to climb through walls

Step 1: Look cute and innocent so the grown ups won't catch on to what you're doing Step 2: Slowly start to crawl - but be quiet, you don't want the grown-ups to know what you're up to
Step three: Poke your head out - just like magic you're on the other side of the wall! Warning: the grown-ups might catch you at this step - so make sure you still have the cute and innocent look you used in step one.
