Two Florida girls got a surprise this summer when they went out paddleboarding - and made a new friend.
Celine Chasteen couldn't believe it when a manatee swam right up to her and put his flippers on her board.
At first Chasteen had thought the manatee was a rock in the distance as she paddled through the waters of Jupiter.
"But then they started moving," she told The Dodo.
"The next thing I know, there's a manatee putting his flippers on my board."
