"They're so fast!" Aoi said, pressing her hands against the glass wall of the viewing area.
"Look at that one!" Aki pointed to a particularly chubby penguin struggling to waddle up a small incline. "He's just like me after eating too much lunch!"
Yuki smirked. "Except he's probably more graceful in the water."
Aki huffed but couldn't hide his grin. "We'll see about that! I bet I could race a penguin and win."
"Not likely," Yuki quipped.
Aoi turned to me, her green eyes shining. "Onii-Chan, can penguins fly?"
"Not in the air," I explained, "but they're amazing swimmers. It's like they're flying underwater."
She gasped, turning back to the glass. "That's so cool! Aoi want to swim like a penguin someday."
