The Wonder Tower which was built in 1926 was once featured in Ripley's. It is located at the highest point between New York and Denver. At the height of its popularity, Colorado's P. T. Barnum Charles W. Gregory would usually stand in front of the tower and check license plates of passing cars.

The cars parked at the adjacent vacant lot are 40 years old and dusty. When Gregory died, the ownership of the tower was turned over to Jerry and Ester Chubbuck. They managed to keep the tower alive by charging one dollar per head per admission.

The interior of the tower is all about Animal Monstrosities. Aside from the two-headed calf at the entrance, Wonder Tower houses Branding Room, Petrified Room, and Indian Room. Jars containing eight-legged pig and one-eye pig are displayed in containers with leaking formaldehyde. A Talking Mummy which is connected to a loudspeaker is now damaged due to old age.

To put some excitement on the visit to the Wonder Tower, Jerry normally conducts a quiz where he points to ten different items and the guests will reveal the identity of the items. This include rooster eyeglasses, camel nose bells, and a walrus penis.
