It's a baby sea lion.
Somehow, the marine mammal climbed off the beach, across a road, through a fence, and ended up on Chris Guimond's porch.
He thought it looked like a dog, but it was barely moving.
Guimond called animal control, who in turn called Sea World.
They swooped in and took the sea lion to their vets to be checked out.
Guimond hopes the pup will be able to return to the sea.
