The episode begins with SpongeBob jellyfishing. He tells a jellyfish to stay off the road because it's dangerous. Some men on motorcycles drive past him, and SpongeBob holds on to one of the men's jackets, ripping an 'M' off of it. He looks at the jacket when he has to let go of it. He presumes it says "The ild Ones," but he soon notices the "W" in his hand and figures out that they are called "The Wild Ones." A fish pops from the ground after hearing this and tells him that "The Wild ones" are a group of vicious bikers who have destroyed cities. SpongeBob runs to tell Mr. Krabs about it, but he does not listen, so he tells Patrick. Then, Mr. Krabs takes the opportunity to welcome to bikers and raises his prices in order to get them to eat there after hearing SpongeBob described them as "ravenous," thinking that he will profit from their business.
After Patrick says that if they dressed up like bikers, they would be the big scary bikers, SpongeBob and Patrick decide to dress in biker attire and ride into town on a paddle-unicycle and a paddle-tricycle, respectively. After the bikers arrive at the Krusty Krab, it turns out that they are old folks.
The actual name of the biker gang is revealed to be 'The Mild Ones.' SpongeBob had the "M" upside-down. The biker that had the "M" ripped off of his jacket gets his "M" back from SpongeBob, and The Mild Ones ride away. Shortly after this, it is revealed that Squidward decided to join with them.
