Plumber Palaeontology

“Plumber Palaeontology” by Nathan Davis aka obvian

A nearly complete fossil found at the bottom of a gorge just beyond the Mushroom Kingdom. Palaeontologists have theorised as to how it perished, with options ranging from abandonment by an overzealous owner (who may have been trying to jump to a further platform) to a fatal over usage of the egg laying ability.
Experts are still puzzled as to how an obviously male specimen was able to lay eggs.
