This was the most amazing thing to me. This dolphin really seemed to take a shine to Sam! He spent a lot of time looking at him and twirling for him while we were downstairs and then when we went back up to water level, he kept coming right up to the wall where Sam was. He'd come all the way up until his body was half on the cement, and he was clicking and squeaking - all right at Sam! It was so fun to watch. I'll never forget it!
