User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-5020152-20121001195238

How can the new monster for MHFO Forward 5, Odeibatorasu, shoot rocks out of its shell?

My theory is that it takes in dirt or sand, and that it's compressed within the Pseudowyvern's body. As for the actual launching, I think it undergoes something like peristalsis (the contraction of the esophagus to allow food to enter the stomach), except with a lot more force.
