Blablanadon

Blablanadon is a pterosaur-like creature who helps Mario and Luigi get to the top of Hoohoo Mountain in Mario & Luigi: Superstar Saga. In the beginning, Blablanadon is absent. Instead, the brothers have to hike up to the top of the mountain where they find the Blablanadon hatching a large egg he found. The egg actually turned out to contain Dragohoho, who attacked the brothers. Dragohoho, it turned out, was really Prince Peasley changed by Fawful's magic. When Dragohoho was defeated, Prince Peasley reverted back to his usual self. After that point, Blablanadon offered to fly the Mario brothers to the top of Hoohoo Mountain at any time. After the Mario Bros.' quest in Joke's End, Bowletta attacked the Beanbean Kingdom from Bowser's Castle. Mario and Luigi had to find Blablanadon and hitch a ride on him to reach Bowser's Castle.

Trivia

 * Blablanadon's name comes from a portmanteau "blah blah blah...", a phrase used to mock incessant, non-stop talking, and "Pteranodon", the name for a type of pterosaur (a related reptile to dinosaurs) not unlike Blablanadon.
