How do you spell...?

The other night while I was nursing Brianna before putting her to bed I was looking at her sleeper. It has a cute little giraffe on one side and most of the rest of the sleeper is covered in a "word search." I was finding the names for various animals including: dog, monkey, lion, giraffe and others. Now, back to my question. How do you spell the name referring to an animal that has black & white stripes and resembles a horse?

I think somebody forgot to use spellcheck!
