Cardboard Play Environments - $12.99

Kids.Woot has National Geographic Play Houses for just $12.99 (normally $24.99).  When my boys were a little smaller, they would have been ALL OVER THIS.  Ever get a new dishwasher or refrigerator and let 'em play in the box?  This is the same concept - except you get to choose from a Medieval Castle, Safari Cruiser or Undersea Explorer.  

• Corrugated cardboard playset easily folds and locks together to provide hours of coloring and creative fun.
• To assemble, simply match numbered tabs with corresponding slots, then push the tabs through the slots until they lock into place.
• Then get out your favorite coloring tools - crayons, markers, watercolors, etc (not included) - and have fun personalizing your very own creation.
• Medieval Castle stands over 3 feet tall when assembled, and includes bonus cutouts of a king's crown, a queen's crown, and two scepters.
• Safari Cruiser stands over 3.5 feet tall when assembled, and includes bonus cutouts of a lion and a lion cub.
• Undersea Explorer stands over 3.5 feet tall when assembled, includes bonus cutouts of a shark and a squid, and the submarine can be worn by a child.
