PLEASE tell me you are not serious, that a Trek novelist wrote that a MUGATO was a crewmember of a starfleet vessel... have these people no shame?
We're talking about Peter David here. "Shame" is a pretty remote possibility.
Almost as bad as whichever early Trek novelist had a horta crewmember... wait, not nearly as bad as that actually, but still bad.
At least the Horta has the advantage of actually being a member of an established sentient race.
I think the Mugato idea is the result of Petey watching a little too much "George of the Jungle"...
