From time to time there are reports of Bigfoot type animals that are undersized. They might be described as Littlefoot. However, they might also be young Bigfoot.
Nick Redfern learned from a man named Barry about an encounter he had with such a creature in Central Park, New York. The creature emerged from a bush. It was about 3' in height. It stared at Barry and then rushed away. Barry does not seem to have noticed a tail, thereby precluding a monkey identity.
