The woman on the left-hand side in the black leather jacket is Erin. Shortly after this moment was captured, Mr. Llama introduced me to her, explaining that she is the manager at Splash Mountain, and helped him plan everything.
Then he started to explain how this was all pieced together. The reason why we stopped for the Birthday Button on Main Street? To help the cast members identify me, so they could give us our own boat! Mr. Llama wanted to make sure that no one else would be in our photo. Additionally, he sent her a picture of me, and a picture of himself in the shirt he would be wearing, so that they knew exactly who we were when we got in line. Erin even said that they had a staff meeting that morning, where they went over the logistics of what the plan was when we were spotted!
