Bigfoot (real name Theodore) is a sasquatch that shows up at the farm in courage meets big foot and becomes friends with courage.
Bigfoot first made his way into nowwhere after he decided to play outside of his backyard, against his mother's wishes. Late one night, he got into the Bagges garbage, and was seen by Courage. While Muriel believed raccoons to be responsible for the mess, Courage had his doubts. Staying as look-out from the bedroom window, Courage heard Bigfoot roar during the night and rushed downstairs, only to find him trying to take Muriel's homemade pie from the windowsill.
The next morning, Nowhere News reported that there was, in fact, a bigfoot "terrorizing" Nowhere, and there was a $25 reward for its capture. Excited to win the prize,Eustace began to prepare, and Courage realized it was Bigfoot at the house the previous night. That same day, an old lady showed up at the door trying to find her lost boy, but Eustace simply slams the door in her face.
When Courage goes into the kitchen for pie, he finds Muriel feeding the Bigfoot, and the two have an extensive food fight. Progressively, the battle becomes friendlier until the two begin a Carmen Miranda-like fruit dance. It's then that Eustace comes in and sees Bigfoot, and attacks with an angry mob. Bigfoot becomes ravange and growls at the crowd, and Courage tries to convince them that he is actually nice. As the mob gets closer, the old lady from before, Theodore's mom, show up and stops the fighting.
The pack attacks Eustace instead, and the two return home.
