It goes like this:

“Back in the box” says Jack in the Box.

“Down Down I go”

Then twist and turn, and twist and turn and I pop up to say “Hello”!

Make sure as you are saying it you lower your body as if to bend, and as you “twist and turn” you “roll” your arms over each other so that your hands go around each other, and when you “pop up” you jump up and say “Hello”! It’s a lot less scary than a Jack in the box toy.  I made this up for my own children and we have since “performed it” for several kids who all loved it!  Enjoy!
