Woooah, Jurassic World 3: Dawn of the Yoshi.Mini-Yoshis are a subspecies of Yoshi. Rather than having the same color skin as the spots on the egg they hatch from, all Mini-Yoshi eggs have cyan, magenta, yellow, and (unseen due to the sprite) black spots, and their skin color is determined by external factors outside the egg before they hatch. This opens up potential for them to have rare shades, hues, and color combinations not seen on normal Yoshis.
From the time the hatch, Mini-Yoshis all have the same proportions as normal adult Yoshis, but they never grow bigger than one brick block tall.
I dig the reason but I'm SO THANKFUL they went with faces, that would have been hella creepy.This is partly confirmed thanks to the Mario Odyssey art book, which stated that originally the citizens of New Donk City were going to be faceless, to demonstrate Mario's alienation and inability to relate to "regular" city folks
