Jurassic Park: Adventures[]
During Eric's stay on the island, during her search for food, Big Momma woke Eric up when her head crashed through the leaves of the tree the boy had been sleeping in. Startled by the dinosaur's sudden appearance, Eric fell out of the tree, sliding down the back of the Diplodocus and landing in some of her dung. As three more Diplodocus joined their leader, Eric identified the sauropod's species and gave Big Momma her name. Afterwords, he left the herd to continue his life on the island.
