Zig and Wikki in the Cow Yr Sc

"When alien pals Zig and Wikki lose their spaceship on Earth, their friendship is definitely in trouble. In order to get home, they must travel through a farm and into a cow, picking up fun facts about ecology (and picking fights) along the way. Nadja Spiegelman and Trade Loeffler's funny, science-based early-reader is packed with fast-paced adventure and facts about poop: what more could a young reader want? Available in softcover and hardcover editions."
