Sure enough, my watery noise-making antics had alerted one of the fiends, and he descended to a branch within striking distance of the shore. With their acute eye-sight I thought I was a goner, and had but one chance to evade a grizzly death. I took a deep breath, and plunged beneath the surface of the water.
And what a breath! I was under for almost 40 minutes and managed to float such a distance down-stream I was safe from the eagle, but most certainly out of my own territory. I did vaguely recognise the area to be part of a particularly grumpy and irritable old sloth's home, so having just had a severe fright and it encouraging the need for my weekly toilet session, I decided the next appropriate tree trunk would suffice.
