Dear GOD!
Why don’t you introduce ALL proposed animals to UR, populating specific, native to them environment? Chakra could host toads and rats, alpine areas – goats, etc.
This would bring more color and diversity to the game, break monotonousness of landscapes, encourage travel and open many opportunities for further expansion of Glitch (quests, badges, crafting, building, trade, interaction, harvesting, etc) that could keep glitchens happy and busy for months and years to come. You could do this in stages and we’ll all impatiently and excitingly wait for a new cute (or ugly) creature to appear. Of course, a supporting structure and a strategy of expansion have to be created in early stage of evolution. You have already created something like this 10,000 years ago, remember?
