Flap is a pickup truck who is painted mainly blue, and has brown eyes. On his sides is a white stripe, and his bumper is gray. His rims are colored silver.
He makes an appearance in the Honkers bar, being served a drink by an employee named Alice Brock. He explains to her that he was left by a woman for a hybrid who was not heard coming.
- His only line refers to the fact that hybrid cars drive quietly, which is why he didn't hear him coming.
- On USA Today, he was referred to as "Bubba". He was called "Flap" in the Meet the Planes book.
