Barnacle's Market
There is a harbor seal at the end of the harbour wall who has been watching people his whole life, and has opinions about what a seal ought to wear.

Why a harbor seal?
Barnacle is a harbor seal, which is the species you are most likely to have met and the most widespread seal on Earth. They ring the entire Northern Hemisphere, hauling out on rocks in Maine, sandbars in the Netherlands, glacial ice in Alaska and quiet coves in Japan.
They are also famously nosy. A harbor seal will surface a little way off, look directly at you, and keep looking. Fishermen have complained about it for centuries. If any seal was going to set up a shop and pass judgement on your taste in hats, it was always going to be this one.
He lies in the banana pose behind the counter, head and tail both lifted off the cold stone. That is not showing off, it is thermoregulation, and you can read the rest of it in his file.
