Let's get a look at these fish! Shinji carefully picks through his memories of getting groceries with Misato - it's been so long since Pen Pen's gotten a whole, fresh fish... They'd been pretty lucky to have access to unlimited fish fillets in Havenwell, and he's not a picky creature by any means, so, hm...

"They all look really good." Nice and fresh, and delicious to eat, probably! And they should all be fit for consumption if they're just being sold to whomever, he figures, so what they really should be getting is something that's the right size for a penguin to chow down on. "Probably... something like these would be just right," he comments, gesturing towards the smaller ones. Something about 15cm? That should do the trick.
