I Know That! — Maryanne Bester

Gaps the Cool Nguni takes his “know-it-all” companion, the cattle Egret, on a gentle journey of discovery
 
Continuing the Bester sisters' beloved Cool Nguni series, I Know That! follows Gaps, the Nguni calf, as he introduces his friend, the youngest cattle Egret, to the library. The little cattle Egret is anxious for Gaps to think of him as smart, and every chance he gets he claims to know almost everything about everything. But when Gaps shows him the exciting world of reading and books, the Egret discovers that there is so much more to get from learning than just shouting “I know that!”
