In The House at Pooh Corner, Pooh reads a note that Christopher Robin made reading, "Gon out. Bisy. Backson" and asks Owl what it means. Owl believes that Christopher Robin has gone out, and is busy, with a creature called a Spotted or Herbaceous Backson, but in reality, he'd simply misspelled "Gone out. Busy. Back soon."
In the movie, Christopher Robin once again wrote the misspelled note, but this time Owl thought the Backson was an evil, mess-making creature who had kidnapped Christopher Robin. The other animals speculated on the Backson's habits, accusing it of stealing youth, "not begging your pardon", and many other things. They then decided to dig a pit and use things Backsons like as bait, trapping the Backson.
As it turns out, Christopher Robin had only been trying to write, "Back soon", though a creature who matched the Backson's physical description did exist. However, this creature was benevolent.
- The Backson has a recurring theme song, which is reminiscent of a horror film suspense cue.
- Despite Owl's thoughts on the Backson, it can be implied that Owl spotted the creature before and assumed he was a villain, even though he was not for real.
- Even though Rabbit often had antagonistic roles, the Backson is the first main solo villain in the franchise, despite the post-credits scene revealing his true harmless colors. Heffalumps and Woozles and bees are villains in a group.
- The Backson may not know what he looks like. This is evident by his comment on the chalkboard of his image that it is a "scary lookin' fella." The reason for this is probably because he does not own a mirror in the woods to see his reflection.
- He was mentioned in Disney Magic Kingdoms.
- If the Backson makes another appearance, he will most likely be voiced by James Adomian using his impression of Huell Howser.
- The Backson was Howser's first and only film role before his death in 2013.
