Several sea horses were on display in a clean, well lit aquarium. One was a bright yellow. While most floated upright, the yellow sea horse flipped over. Once.

"Did you see that? That sea horse flipped over."

"Sea horses don't flip. Not unless there's a current."

"Come here. Come here. I will show you. Hey! You! Sea horse. Come on, flip again."

"Don't tap on the glass. One of your rings could scratch it."

"But I saw it flip. I swear on my poor dead mother's grave that it flipped."

"Sea horses are not really horses you know."

"Of course I know that. They're fish. I think. Hey, you know I once found a plastic sea horse in a box of dry cereal. Back then, when I was a kid, they put toys like that in boxes of cereal."

"I remember those. But those were smaller than the real thing. And plastic."

"And lots more colors."

"I wonder if, back then, they knew about land fill and plastic? You suppose they would have ever thought that their plastic sea horses might some day be found floating among trash in huge islands of trash in the middle of the ocean?"

"Recycling didn't start until the '80s, or was it the '70s?"

"What if poisons, in those plastic sea horses, caused mutations in real sea horses."

"You mean like giant sea horses hopping over the land, eating people and cows?"

"Maybe just smarter, or more yellow, or easier to catch."

"Oh, look. Over there. An Octopus and its making a peace sign."

"Where?"

"Come on. It's in that tank."

The yellow sea horse had floated upright throughout all this conversation. Now the yellow sea horse flipped over. Once.

"Mommy! Mommy! I just saw that sea horse flip over!"
