Courage The Cowardly Dog

Courage throws a lot of objects at Bigfoot including a Chicken which has a close resemblance to The Chicken From Outer Space shown in the Pilot episode with the same name, after the Chicken was Fried, or was it just a Chicken that for some reason has been cooked.

In "Hothead," while Courage is playing the harp, he says "stay calm, stay calm," but his mouth doesn't move.

They clearly show that they don't have any neighbors. Then, out of nowhere, an angry mob appears to take Big Foot away (edit: They might not have any neighbors, but they certainly have people that live in the surroundings. Eustace could have gone and called the most nearby people to help him catch bigfoot).

In "Courage Meets Bigfoot," Courage found a footprint, and it was Bigfoot's. But the footprint was larger than Bigfoot's actual foot.

At the end of "Hothead," the house explodes. When it explodes, the windmill stops turning. But according to the segment "Windmill Vandals," if the windmill stops turning the vandal skeletons will attack. When the windmill stops, vandals didn't attack.

In "Hothead," Eustace's hair was curly. But in both "Bad Hair Day" and "Farmer-Hunter, Farmer-Hunted," he had straight hair.
