What's da matter, don't we taste no good?
Based on her concept art, Tesma has a large body, droopy eyes, and a snout nose. Her colored concept art shows her with pale tan fur.
When Simba is exiled from the Ndona Pride, he encounters Tesma and her family. The meerkats at first aren't sure what to make of him, and when Simba denies eating meerkats, Tesma asks whether or not they taste good to lions. Finally, the colony concedes to letting Simba stay, and the young lion takes up residence with the wary but friendly meerkats.
The Lion King Wiki has a collection of images and media related to Tesma.
