There was an Old Lady Who Swallowed a Trout! By Teri Sloat, illustrated by Erynold Ruffins

From chapters.ca:
A bright, energetic retelling of a beloved children's rhyme, with a Pacific Northwest twist. "There was an old lady who swallowed a trout / That splished and splashed and thrashed about." Everyone has heard about the old lady who swallowed a fly, but there is something particularly fishy about this old lady... Beautiful illustrations in this story capture the scenery and wildlife of the Pacific Northwest. The buoyant text jumps along as the old lady swallows a salmon, an otter, a seal, a walrus, and more, until eventually she swallows the entire sea and the trout swims free! With a unique and fascinating setting, this pure flight of fancy gives a fresh look to a familiar poem.
