Mr. Peaches was a large orangutan that belonged to Oswald P. Burlington, and was the mascot of the Benevolent Lodge of Mystery. He lived in the 1880's and is reported to have died of old age. Grief over his death is supposed to be the reason Burlington broke up the Lodge.

- Mr. Peaches apparently got his name because peaches were his favorite food. He was a big eater, and this trait was shared by his fellow Benevolent Lodge of Mystery member Scotty O'Rourke. This is a parallel with Scooby-Doo and Shaggy Rogers.
- It could be said that Mr. Peaches could talk since he said his name while running toward the ghost train, although this could be an a effect of the terror wood.
