Additional context
Puffins swim through the water much like they fly through the air, so they could probably just completely ignore water blocks as existing.
Puffins have been caught via baited hooks in the water, meaning they could technically be fished up.
They've also been caught with thrown nets, perhaps an addition to consider.
