There was a pile of brown and yellow leaves in the ditch. The boa constrictor settled into the middle of the pile to get some sun. It was a good place to look for toads or rats while he couldn't be seen.
Suddenly there was a scuffle on the pavement and a little boy jumped over the boa. Surprise! But boas aren't hasty. The boa looked around calmly and planned his escape. There was a road at his left. The little boy had continued on his walk up ahead. But to the right was a fence touching the branches of a large tree and it looked just right.
There were many holes in the fence, each the same size. The boa tried one and then pulled out. "It would never do." he thought. His lower lengths were too fat to fit. So he tried another and another. At last one suited him and he oozed through, slowly. Back and forth he went, in and out of the fence's holes until he had coiled his body up one of the posts supporting the fence.
The boa nosed across the top bar of the fence until he found the tree branch, curling and coiling all the way. It was a wonder the fat snake could balance so gracefully and wind his way onto a slender branch that just supported him without snaping. But boas are wise and sensible. The boa wouldn't have chosen a branch he could slip on, especially since the little boy was watching him now.
When the boa was successfully in the tree, he felt safe again. Boa constrictors prefer to make surprises than recieve them. Next time the boy passed he scanned the tree, but if the boa was there he didn't show himself. How many boas can you find?
