My favouritest game in the whole wide world

Rules are simple:

• You MUST have to have something in our mouth, preferable something that everyone wants. In this case, my chewie (mum: you mean Jaffa's chewie)
• The tunnel MUST be utilized
  
• Turning around in tunnel IS allowed only if you are cornered
  
• Hiding in tunnel IS allowed

Demonstration of HOW the game should be played. Please ignore STINKY, he obviously doesn't get the game.
