Crocodile Teeth

A crocodile with no teeth?
Poor Grinder N Grater is old and has lost all his teeth. And he is sick of being laughed at by the other animals. And tired of being hungry. His little bird-friend Cheenchi Chiriya tries many replacements. But thorns are too sharp, pebbles are too smooth, and dinosaur teeth are too big or too small. And then she has an idea which takes all the animals deep into the forest, into a dark, dark cave with a magic door. What’s the plan?
