The title is a play on Sylvester's famous line, "Sufferin' succotash."
In Autumn 1937, Sylvester Sr. and Sylvester are on a family camping trip. Sylvester Sr. is relaxing while Sylvester goes into the forest to collect firewood. Sylvester starts to hear growls and rustling, which terrifies him. When he turns around, he sees a large beast and panics. As he's running away, he falls into a giant foot-shaped hole.
In the present day, Daffy Duck, hosting Mysterious Phenomena of the Unexplained, questions whether Sylvester really saw Bigfoot. Sylvester tells Junior about seeing Sasquatch, and Sasquatch Sam, a Bigfoot expert, arrives to confirm the sighting. Daffy offers a $10,000 reward for conclusive evidence of the creature's existence. Sam pretends to go into a cave to capture the beast, but the growls are really coming from his stereo. Sam dresses as Bigfoot in order to claim the reward but then is confronted by the real Bigfoot. Daffy closes the show stating how there is plenty of fake evidence of Bigfoot, then the real Bigfoot appears behind him.
- In the original webtoon, there were interactive segments which show pictures of Bigfoot.
- This is the only appearance of Sylvester Senior.
