Box

Cardboard box = packaging, play house, karate kick bag and new best friend = hours of free fun

After tiddler having fun trying to fit inside the box that contained the replacement trampoline net and use it as a house the boys decorated it as a black belt karate sensei and were taking it in turns to basically kick the crap out of it.

They were then arguing over who was going to sleep with it tonight - apparently boxes do have feelings.
