The Dinosaur Leg Bone

Froggy the Gator wakes up in the middle of the night with a pain in his leg! But luckily, Daddy the Gator is there to reassure him that what he's feeling is something called "growing pains." This inspires Daddy the Gator to tell Froggy a story, about another kind of animal that also needed some help with his leg bone: an ancient Brontosaurus.
