I am literally lost in the desert on a horse with no name.

They can walk up stairs.
Not sure what to do with that information...

Give it a lick. It tastes just like raisins. It's amazing.

Using lasso on Equus can help you a lot in taming progress, as the lasso can drag many creatures even if they are unconscious!

Can actually be used for fighting. A pack of Allos vs an equus is much more equal than expected - you can knock the allos out and just walk away. Just make sure you have a high level horse.
