A plucky pebble shows true grit as he travels the country trying to find out if he fits in with any of his famous rock-formation relatives. Rocky comes from a long line of rock stars! Uncle Gibraltar, Aunt Etna, and Great-Grandma Half Dome are just some of the legendary rock formations he calls family. It's no wonder he wants to matter in a big way too--but it's not easy trying to get a foothold. Rocky gets tossed by The Wave and driven away at Devil's Tower--but he's determined not to allow these pitfalls to chip away at his confidence. Rather than feeling crushed, he keeps on rolling, hoping to become the rock-star he knows he's meant to be.
