Blablanadon

Blablanadon is a pterosaur-like creature who helps Mario and Luigi get to the top of Hoohoo Mountain in Mario & Luigi: Superstar Saga. His name comes from a portmanteau of "blah blah blah", a phrase used to mock incessant talking, and "Pteranodon", the name for a type of pterosaur.

In the beginning, Blablanadon is absent. The brothers have to hike up to the top of the mountain where they find him hatching a large egg he found. The egg is shown to contain Dragohoho, who attacks the brothers. Dragohoho, it turns out, is really Prince Peasley changed by Fawful's magic. When Dragohoho is defeated, Prince Peasley reverts to his usual self. After that point, Blablanadon offers to fly the Mario brothers to the top of Hoohoo Mountain at any time. After the Mario Bros.' quest in Joke's End, Bowletta attacks the Beanbean Kingdom from Bowser's Castle. Mario and Luigi have to find Blablanadon and hitch a ride on him to reach Bowser's Castle and back when they escape while Prince Peasley detonated the castle. Because he flys the Mario and Luigi to Bowser's Castle, if they want to go to the top of Hoohoo Mountain, they will have to hike.

Trivia

 * He essentially plays the same role as the Zeekeeper as they both are allies who fly up the Mario Bros to Bowser's Castles in their respective Mario and Luigi games.
