Suddenly, everyone is more curious then scared, and they croud around Spike to stare at the unusual sight. Petrie excitedly says "Egg? Me find egg?". He exclaims to Petrie that it isn't a rock, it's an egg. All at once, Littlefoot knows what Spike had all along. Spike, however, carefully climbs on top of the rock and stretches himself out, covering the top and sides as much as he can with his stubby legs. They all skid and scramble away from the rock, certain somting awful is about to happen. Cera screams, and Littlefoot yells "Look out!". Spike then taps the rock again a little harder, and to everyones surprise, the rock taps back. As everyone holds their breath, Spike reaches out and taps the side of it nothing happens. Spike doesn't seem afraid though, and sniffs and snorts the air while circling the rock, getting closer and closer to it. Littlefoot tells Spike to be careful, and that it might be dangerous.
Littlefoot is too busy watching Spike to hear anything though, who is going towards the egg. He then begins to ask Cera, Ducky, and Littlefoot if they know, but getting no response from them, he angrily calls Littlefoot's name again, and asks if they are listening to him. Petrie questions what type of rock moves by itself, and concludes that he doesn't know. Petrie squeakly tells Littlefoot that the rock moved, and Ducky quickly runs up to Petrie and confirms that it did, and that she saw it too.Ĭera huffs that they all saw it, not wanting to be left out of anything important. She studders while trying to explain the situation to Littlefoot, until he finally asks her what it is, and comes over to the rock himself. Cera shakily tells him that they've got it, while not taking her eyes off the rock incase it rolls again in her direction. Littlefoot impatiently asks them what they are waiting for, and tells them to hurry up, asking where the last rock is. Spike and Littlefoot then peer over the edge of the hill. Petrie frightenedly gulps that it moved, not knowing what to think. Cera then whispers to the others if they all saw it, and steps back a little. Ducky, Chomper, Cera, and Petrie all see it though, and for a moment none of them move, breath, talk, or blink an eye. It moves only very slightly first to one side, then the other. Just as Ducky reaches for the stone though, something very strange happens the rock moves. Petrie is proud of the rock and doesn't think Ducky can hurt it just by touching it. She begs Petrie to let her touch it, which he does. Ducky is very insterested in the rock, and thinks it's very pretty. Petrie steps back from the blue and gray rock, he comments that it has speckles on it, and it is smooth like his beak. He then says to his friends, "Look at MINE!". Petrie starts to inspect the rock it is smooth and warm to the touch, unlike the other rocks which have been cold and rough, Petrie thinks it's strange. He puts all his weight against it with his back, and is surprised how easy it moves compared to the other rocks they have lugged around all day. Petrie is busy with a large speckled rock that he found lying in a soft, shady place under a bush. Later, Littlefoot calls out to his friends that there are only a few rocks left to go until they finish their fort. They make the fort bigger, taller, longer, and stronger. Littlefoot and Spike stay at the bottom of the hill, because it is their job to take the rocks after they roll to a stop next to a large tree, and push them into place. Between their puffing and grunting they shout "Look out below!" and the heavy rocks roll down. The five friends work all afternoon, gathering rocks of all shapes and sizes and putting them at the edge of the grassy slope. Even Cera has to admit that Littlefoot is smart for a Longneck.
His friend Petrie agrees, and so do his other friends Ducky, Spike, and Chomper. Littlefoot explains that it will be easier to roll rocks down the hill than roll them up. At the beginning of the book Littlefoot points to a spot below a little hill and says "Let's build out fort right here,".
