While playing, Splash senses something is wrong and quickly swims out of Dunk's way as he comes in for a hard landing. The strange thing is that Splash wasn't even looking in Dunk's direction, so how did he know he was coming?

Gush soon explains that Splash isn't a superhero, but simply has a lateral line sense, which is common for fish. / Ripple feels like she is struggling to be part of her group of friends, then meets a shy oyster named Pearlene, who also feels isolated from those around her.

She does, and finds that, despite her rocky, mucky exterior, she has a great inner beauty: not just the pearl inside of her shell, but also her warmth and compassion for everyone.
