This whole thing about the dictionary is extreeeeemly interesting. Going to look at just a few.
No Coati or Howler on the list though.

No Ocelot or Squirrel (Squirrel Monkey).
Nothing for Markhor. No Musk/Muskox or Walrus either.
Honey is also in the diction but could related to either the Sun Bear or the Bee scenery piece. Was thinking of Honey Badger of course.
Can't tell about Spectacled Bear or Brazilian Porcupine, since those words are already in use. Andean is not in the dictionary. Same for the Cobra. Same
Nothing for Pelican, but there is a duck but that may related to the platypus.
Most interesting that I don't see mentioned yet, Echidna is in there. Eagle is in there as well, not sure if that relates to something already though. No Toucan or Cockatoo. Macaw as mentioned, but, and I may be wrong here, isn't there some kind of scenery piece with them?
Okay that's going to be it for now. Time to get to actual work!
