While he's still able to waddle relatively easily, Simba lumbers toward the middle of Pride Rock's ledge. He plants his front paws ahead of him, drags his mass forward, and then repeats. His blubbery body wobbles like mad with every ponderous motion. Once Simba is about halfway between the edge of Pride Rock's ledge and the cliff wall behind him, he stops waddling and resumes feasting. At first, Simba's growth threatens his mobility. His rear fattens, making it even harder to move his hindlegs. His belly bulges out across both sides of each of his legs. His gut gets taller as well, to the point that his paws lift off the ground. Gradually, however, the rest of Simba's body starts to catch up with his blubber. His legs lengthen, allowing his paws to touch the ground again. His head gets bigger and his back grows longer, making him taller than before.
