The hotdog henchmen are muscular fish who wear hot dog costumes. They wear it to show they are part of the weenie hut employment. One of them is dark blue and the other one is light tealish green on the inside of the costume.
They are first seen outside of SpongeBob's pineapple house. They kidnap SpongeBob in a hot dog bun after Mister Weiner fires him, not realizing that his small food creation would become a huge success, and bring him to Mister Weiner.
They are the only henchmen that are sent by an employer to capture SpongeBob, as Señor Taco, Pizza Pete, and Noodleman all catch SpongeBob on their own, without any assistance.
