I just got a plantsim that isn't a plant

I just had a new neighbor visit and one of the housemembers had a moodlet that she just met a Plantsim because this woman was a plant lover (funny because she has been trying all week to kill the Mother Plant in StrangerVille  but that is a different issue...she still loves plants).  But this alleged PlantSim doesn't look anything like a PlantSim.  She is a normal pink skilled human looking sim.  I wonder if that is some strange glitch and she isn't really a Plantsim at all or something else?  She didn't have any problems chowing down on the Garden Salad we had for dinner when she visited.  Maybe she is a plant cannabal?
