Only humanoids weighing between 130 to 270 pounds (59 to 120 kilograms) and with heights between 5 feet and 4 inches to 6 feet and 2 inches (1.6 to 1.9 meters) were considered acceptable.
What about Brainstealer dragons? Mindwitness? Squidlings? Uchuulons? Urophions?
The creatures I have listed do not meet the criteria described, but are still considered Mind Flayers.
