Was it big?
Did he see it? What if he had gone over to check it out? I KNOW Oscar would have, little hellion.
I always worry about taking Oscar swimming in the ocean in som places (shallow beaches are not too much to worry about) here, we have baby (I hear they are tiny) Great Whites, Seals, and Orcas- they are what I really worry about since they eat seals and sometimes other whales too. I think I'll be picky about where I swim him now, you've got me paranoid.
