The Stomponadon is an enemy Banjo and Kazooie encountered in the video game; Banjo-Tooie. It is a gigantic dinosaur-like creature that resides in the Stomping Plains in the world of Terrydactyland. However, unlike most of the dinosaurs that Banjo and Kazooie encountered in Terrydactyland, the duo never see Stomponadon's full body, but instead it's large foot. Stomponadon is also known as the Triassic Steamroller.
When anyone enters it's territory, the Stomponadon will attempt to stomp and crush them with it's large foot. Banjo and Kazooie had to get to the other side of the Stomping Plains in order to get the items such as a Jiggy and Jingo. As they enter the plains, the Stomponadon stomped it's foot down onto the plains, warning them not to continued any further. Despite the giant dinosaur's warning the two pressed onward. As they processed through the plains, the Stomponadon attacked the duo. If Banjo and Kazooie get stomped by the Stomponadon, it'll result in them losing all but one Honeycomb (, which is their life bar). And if they get stomped again, the result is fatal. However, there are some areas that Stomponadon can't reach Banjo and Kazooie, including the main entrance, the end of the plains and a bunch of footprints that are too small for Stomponadon's feet to go through. Eventually, Banjo and Kazooie were able to cross the Stomping Plains and survive the Stomponadon's assault. However, after they acquired the Jiggy, they had to return to the other side. Thankfully, the two spotted a pathway which led them back to the entrance, without crossing the Stomping Plains. It's unknown what happened to the Stomponadon after this incident, though it's likely that it's still alive, attempting to stomp on any intruder who dares to enter the Stomping Plains.
