Zombies, Do they bleed?

[kek]

Do we know for a fact that they walked along the ocean floor? If they were swimming shallow and bobbing up for air would Pegs and Michael even noticed?

We don't know for sure if they were walking along the bottom. I think theres a good chance they would have noticed if they were on the surface though, Pegs and Michael were swimming through the water toward the boat, any odd movement probably would have caught their eye. maybe the zombies just dont need as much air? or, depending how far the island was from the boat, maybe the zombies came while michael and pegs were inside the boat. Riley did not mention seeing any zombies though before they arrived at the boat did she? and wouldn't she have seen them if she was looking towards the boat from the shore?
