My Pet Dolphin 2 review. Classic Game Room presents a CGR Undertow review of My Pet Dolphin 2 for the Nintendo DS developed by Starfish and published by 505 Games. My Pet Dolphin 2 is a European release in which players control—no surprise—a pet dolphin. But the game isn't exactly what you'd expect from a "pet game." In fact, My Pet Dolphin 2 is more about exploration. You explore the oceans and all their labyrintine nooks and crannies, searching for hidden items and helping marine life with their problems. You can also play with your pet dolphin, but My Pet Dolphin 2 is a lot more Ecco than Nintendogs. This video review features video gameplay footage of My Pet Dolphin 2 for the Nintendo DS and audio commentary from Classic Game Room's Derek.
