At the moment I only have mammals, but I could mention that each is a mammal.
I'm thinking I should just do the animal names in Spanish. Blasting kids with 5+ sentences for each animal could be a lot, but hearing horse in both languages while looking at a horse running around could probably be effective for teaching.
The animals I have [4 horses, pony, sheep, pig, german shepherd, gemsbock antelope, regular antelope, 2 donkeys, a red fox, a white wolf, ] I have to stop there. Just getting audio for each is getting out of hand.
The stable scene is the educational part, I have another mini game I'm attaching where you wander around a pasture with a tap controller(camera looks down from above, touching screen moves in that direction). If you stand close enough to an animal, you can touch it to start taming. If you succeed the animal will follow you around. If you go back to the farmer/stable it puts the animal in the stable and gives you some points. Eventually I'll have the farmer give quests like "gather all the sheep" but for now you just find animals and tame them for some arbitrary points and you raise a taming skill the more you tame. I also have 2 riding games where you steer a pig or horse from a first person perspective but it's too complicated for toddlers.
So right now I'm at:
Name, diet, where they're from, baby name, group name(herd, flock, etc), mammal, male, female. For each of the 16 animals I have. They also run around playing idle, graze, walk, run, jump animations and play various sounds.
Edit:: maybe a video would better show how I'm presenting the info. I don't have the audio for reading each animal's text yet, but on the kindle fire the animals look like: https://www.youtube.com/watch?v=BEvT0w7FmxQ&feature=player_detailpage
Each speaker symbol in the image below is an animal out in the pasture. You don't see them all at once, the camera looks down on the player from directly above.
