Megadongo

Megadongos were an titanic ancient subspecies of Dodongo that went extinct sometime in the distant past. The exact cause of their extinction is unknown, but likely linked to the incessant wars between the native races of Death Mountain. The only known physical example of a Megadongo is the massive fossilized skeleton in Dodongo's cavern.

Physiology
Megadongo's were massive creatures, dwarfing even King Dodongo. The individual whose' remains lie in Dodongos' Cavern was the size of a small city. Aside from their size, they appear similar to other Dongos, with a reptilian form, four limbs, and a single horn cresting their head.
