Intro: SpongeBob Best Friend Mystery Box.
This is a very simple picture hidden inside of a box.
Step 1: Step 1: the Box.
You will need a box, paper, coloring materials, rubber band, and scissors.
Cut the top so you can make a lid, and you can put details on the box.
Cut the slit, then cut the rubber band (taping the rubber band on the slit).
Step 2: Step 2: Pictures
Draw the same picture. Put the picture inside the box, underneath a flap.
And there you have it! Now you can trick your brother and/or sister!!
