Although Dark watched the sea lions with his typical, unbothered expression, his eyes were bright as he saw their dives and tricks. When the trainers explained the differences between a sea lion and a seal, they had the sea lions mimic seals movement patterns. When they had them vocalize, the tiniest smile pulled at the corners of his mouth. Meanwhile, Ivy watched wide-eyed with a big grin--since she had learned how to, anytime the audience clapped, she did too, and since Alec was oohing and aahing, she'd make little noises just after he did. When the sea lions honked, she laughed so hard she tipped over out of Dark's lap and her head dropped into Alec's lap.
Throughout the show, some of the tricks would be done to music (bizarrely, it was primarily to 80s pop songs) so all the sea lions would be diving, leaping out of the water, or waving together. They also had the sea lions do "impersonations" of other animals, such as one of them swimming with one fin held out of the water to "be a shark."
At a few points in the show, the sea lions would hop right up against the glass, so their heads were hanging over, and once the sea lion was allowed to jump all the way over and parade (still at a safe distance) down the length of the walkway before hopping back into the tank.
