You beat me to this one. The title of the page I was looking at is LORE FOR OCTOBER. Weird!
As soon as he said it I automatically remembered this tale...
The Rabbit was so boastful that he would claim to do what- ever he saw anyone else do, and so tricky that he could usually make the other animals believe it all. Once he pretended that he could swim in the water and eat fish just as the Otter did, and when the others told him to prove it he fixed up a plan so that the Otter himself was deceived.
Trick or Treat...Halloween theory...thoughts??
