(which is fairly reasonable for a Tiny biped in MM- the size table has Tiny as starting at 1 ft tall and 1 lb in weight, and going up to 2 ft tall and 8lb.)

So, if these creatures are smaller than standard Tiny creatures in both height and weight, a Diminuitive size is quite reasonable.
Yeah, my reasoning were that they are bipeds and 20 cm tall. I figured that to be around 8 inches. I can't find the weight, though.
