Zach the Yak

Too many yaks stacked on Zach's shack can be a disaster. Zach the Yak is one of the Bee's Knees Rhyming Readers, a series of picture books for early readers. The books are designed to appeal to children's sense of the absurd and at the same time increase their word recognition vocabulary through rhyming words. The series is also useful for English as a Second Language learners.
