The Mechanical Toothless Puppet is a wearable puppet used for the Snoggletog Pageant.
After working out some of the details of the Snoggletog Pageant, Hiccup builds the mechanical puppet in Gobber's forge on New Berk. It played a major role in the Snoggletog Pageant, until the stage caught on fire, and it crashed to the floor. In a daze, Hiccup, who was inside the puppet, stumbled off the edge of the stage and over the cliff. Toothless saw what was happening and rushed to save it. Without knowing Hiccup was the person inside, Toothless gently deposited it back on the stage as the fire was being put out. Still in a daze and now surrounded by smoke, Hiccup didn't realize who saved him. But Toothless suddenly recognizes his best friend's scent, and starts affectionately rubbing against the puppet, and licks it just as Hiccup passes out, collapsing onto the floor while still inside the puppet. Toothless then stands in for Hiccup for the remainder of the pageant, while all the Vikings still think he's the puppet due to the smoke still lingering from the fire.
The puppet fashioned out of black steel, leather, and wood. It has large googly eyes, four barrel shaped legs, and retractable wings. It is is meant to be worn by Hiccup, with levers and strings inside to help it realistically move and even breathe fire. During the Snoggletog Pageant, it is strung from the rafters of the stage, giving the appearance of flying.
