Having been to the Newcastle get together I landed this bug, and my composition follows.:
After being insulted the balls decided to get together and bounce around the box a little. Puss in Boots was complaining loudly, and after Donkey again asked for silence the balls bounced into Puss, the unconcious Puss granting Donkeys request for quiet. Driver and Shrek were hiding in the corner behind Donkey and managed to avoid the flying balls.
Donkey had been right however and there was someone coming, as the cache was lifted everyone fell into a heap in the corner of the box. As the cache lid slowly opened, everyone froze, making sure not to give away their special abilities.
