Once upon a time, a small robot named Bolt was cleaning a dusty vampire castle. He had never expected to meet a young dolphin named Splash, who was lost and far from the ocean. 'I was following a pod of whales on their migration,' Splash explained, 'but I got separated during a storm.' Bolt tilted his metal head and said, 'A pod? You mean a group of whales? That sounds like a family.' Splash nodded, 'Yes, and we are all mammals, just like you are not.' Bolt beeped in confusion, but he liked Splash immediately.
Suddenly, a loud roar echoed through the castle. A giant monster with three eyes and purple fur appeared! 'I am the Grumble Beast, and I will eat this castle!' it shouted. Splash squeaked in fear, but Bolt rolled forward bravely. 'If we work together, we can defeat this monster,' Bolt said. 'However, I need your help, Splash. Can you use your echolocation to find its weak spot?' Splash clicked and listened carefully, then pointed with her fin. 'Its weak spot is behind its left ear!' she cried.
