Dumbosaurus ignoratum

The only remaining member of the genus: Dumbosaur. This has been found to two factors:

1. Predator evasion

Ignoratum escapes predation by not using its powerful spines as most animals would; but by rolling moronically onto its back, exposing its soft underbelly. Such a depressing display of sheer stupidity leads to the hungry predator walking off, shaking its head in pure disbelief.

2. Food-finding skills

Dumbosaurus ignoratum is such of a lead bucket when it comes to the IQ department. So much so that it is incapable of feeding itself sucessfully, often feasting on rocks and snorting mud. As the slack-jawed hulk of a corpse ambles through the forest, slime molds in the vicinity feel sorry the beast, attach to its lower jaw and guide it to more edible food sources.

There is only one currently-living specimen of Dumbosaurus ignoratum: Bludgkin, the idiot-in-residence of MADhouse.
