In 1962, Bruce Hallenbeck was 10 years old and loved to play in the woods of Kinderhook, New York. He and his cousin were playing behind Hallenbeck's house when a loud whistling sound pierced the air. The children stopped in their tracks, obviously confused by the noise. While looking for the source of the sound, the children saw a mysterious figure behind a tree. It was white object that was peeking around the tree at the two kids. Hallenbeck reported that the creature had no eyes despite the fact that he thought it was watching them. They quickly ran back to the house.
For two years, nothing else was seen. Until an anonymous witness claimed to see a floating white blob moving toward him while he was on a hike. He ran away in fear but returned to the scene with his friend, armed with a shovel and pitchfork. Upon seeing the creature again, the two men dropped their weapons and ran away.
Other sightings reportedly also took place in 1964. Some witnesses claimed to see the creature in 1978 where it was described as "bell shaped". There were even sightings of the Kinderhook Blob as recently as 2017. Witnesses Owen Farley and Anthony Malanowski described the creature as 7 feet tall. It floated toward them at a high speed and the two men ran away as fast as they were able.
