Cryptic help needed!

I’m fairly new to cryptic crosswords, and I’m doing a challenge where one of the clues seems like a cryptic clue to me, but I can’t for the life of me figure out what it could be.

The clue is:

“Look mum! I can see the ocean!”

Maybe I’m barking up the wrong tree, but thought I’d reach out to the experts to see if you had any ideas! Appreciate any help you can give.
