Zig and Wikki in The Cow Toon Books Level 3

Can cow poop help two friends patch up their friendship? 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 underground and through a cow, picking up fun facts about ecology (and picking fights) along the way. Nadja Spiegelman and Trade Loeffler's funny science-based easy-reader is packed with fast-paced adventure and facts about poop: what more could a young reader want?

Nadja Spiegelman likes cooking, writing, and decorating her apartment with furniture found on the street. She grew up in New York City, but loves going on vacation to the countryside. Once, when she was very young, a cow mistook her bright yellow dress for a flower and tried to eat her. She's still a little afraid of cows, but she'd like to learn how to milk one.

Trade Loeffler is also the creator of the all-ages web comic Zip and Li'l Bit, and lives in Brooklyn, New York, with his wife, son, and their dog, Boo. Trade grew up in Livermore, California, the home of "the World's Fastest Rodeo," an event complete with bull riding and wild-cow milking. But although he grew up in a "cow town," Trade never considered himself a cowboy - even though he does own two pairs of cowboy boots.
