Based on the true story of The Wright Brothers, The Red Guy narrates a documentary about The Wright Bros. and the Rong Bros. (Weasel and I.R.), competing to see who could invent the first plane.
Chicken hates taking a bath, so he decides to waste his time. Cow, Mom, and Dad are all desperate to go to the toilet, and attempt to persuade Chicken to take his bath.
Dad cannot get along with his new neighbors, who happen to be clowns. Cow falls in love with the clown son when it is learned they go to the same school.
Weasel is an aircraft pilot, with I.R. as his co-pilot. Their job is to bring passengers upstream because of a dam, created by beavers, getting in the way. However, things go wrong when there’s too much weight aboard.
Chicken, Flem and Earl are on their first day of junior high school, where in P.E, they play dodgeball. While they are in the showers, their clothes are stolen.
While trying out the Pork Butt catapult, Chicken is accidentally swallowed by Cow. Mom and Dad take her to a doctor (the Red Guy), and they must get Chicken back out before he journeys through all four of Cow’s stomachs.
Cow still has a security blanket (which happens to be Supercow’s cape), but Chicken objects to her still carrying around such an item at her age, which leads to it being thrown out on the way to school. While Cow is depressed, the principal (the Red Guy) decides to torment Flem and Earl.
Cow, Chicken and their cousin Boneless Chicken travel to the Lava Park, where they learn how to fly a kite. Unfortunately, when Baron Von Non-Leiderhosen (the Red Guy) loses his kite, he uses Boneless as one for a tug o’ war contest.
Chicken hosts a magic show in front of his friends and family. It soon becomes no laughing matter when he makes Cow’s udder disappear, which ends up on the Red Guy.
Chicken wakes up one morning and finds an egg underneath him (placed there by the Red Guy). This leads to him dressing up as a girl, as well as going out on a date with Flem and Earl.
