Ah, the wendigo. Reminds me of stories my husband tells of his childhood at U.S. Air Force in Japan, when tales of the Kappa wove itself into his earliest memories. The Kappa, a river monster based loosely on the Japanese giant salamander, had a beak for a mouth and was known for kidnapping children. Riffing on the legend, fear of the Kappa was used to reinforce all types of behavior. In my better-half's case, it meant wondering whether the Kappa would come after him if he didn't finish his dinner. All in good fun, to be sure, but an enduring childhood recollection.
