Mo's Creatures has stuffty Textures and Awkward models
For the first three mobs only... (lion, bear, ogre.)
I have talked to the creator specifically, he has said he will revamp their skins and behaviors when he has time, plus more. For example, while revamping the lions' weird textures and spawning everywhere there is grass, he will also add things such as jungle-specific Jaguars and Tigers.
Geez, who knew first impressions made such a difference... it seems the people who dislike it pull the "stuffty textures" excuse every time. Did you and the rest of them look at the mod in its baby stages and never go back?
The past 5-6 creatures are all very well made and fit perfectly with default Minecraft.
