Fletcher flew to the back of the pet store, disappearing behind the shelves where the fluorescent lights went dark and everything basked in the blue glow of the fish tanks. When Nos and Two caught up to him, he had his face pressed against a cubicle of snails.

"Mom! Dad! These are exactly the ones I was talking about!"

"Yes, darling, but don't you want to see some of the fish before you pick out your snails?" Two suggested, pointing toward the section of colorful, tropical fish.

"Come on, Mom, fish would only make the tank dirtier and probably eat the plants."

Two did her best to seem like she didn't mind either way, but couldn't quite mask her aversion to the mollusks. Nos hovered forward, putting his hand on Fletcher's shoulder. "Why don't you just take a look? There are a lot of different species here, you never know what you'll find."

Fletcher contemplated it for a minute before conceding to check out some of the other creatures on display.

Nos winked at Two, who smiled in relief.

"Whoa... look at these guys!" Fletcher called from a few tanks down. Some dark, streamlined fish rested in piles around the bottom of the tank, others pressed flat against the glass, grazing the surface with mouths like suction cups.

"Ple-co-sto-mus. Cool!"

Two groaned, looking up at Nos. "Why couldn't he just want a goldfish or something?"
