A comparison has been made for Dodongo from The Legend of Zelda: Ocarina of Time. This compares each part of Dodongo between the original and the newly rendered one in Ocarina of Time 3D. Here's an excerpt from the comparison:
"The new version includes an actual tongue. You can also notice that the inside of the mouth provides more detail and better textures. One can tell the top part of the mouth from the bottom part now. The teeth provide more realistic looking textures in the new version also. One last note about the mouth is that the outer edge appears less 'blocky' and are smoother."
