Sound the alarms, sound the alarms!
This was the first thought of several who first spotted the tiny dots fast approaching.
But soon, they recalled the orders given to them.
Sound travels incredulously by air, especially when they're so close to the seas.
Ringing the bells should be the last signal given only when the enemy is already so close and there is great urgency to warm everyone.
Very quickly, one of them slid down the treehouse post and ran towards another pole note too far away, where he then flicked the switch on and off severally.
They used light to communicate.
5 flicks mean enemy attacks!
They were to continue flicking like so until the next set of treehouse people took note.
But that's not all.
One would think that the gun idea of using cans and things to talk was something only kids could do, but you would be wrong.
