On a sunny day, people came to see a massive blob in the lake. The blob was red, blue and yellow. It was ready to jump on.
Anticipating their turn, the people were excited because it would be fun. When one person jumps down, the other person on the other side of the blob will fly into the air. Tumbling straight down they made a giant splash. It was so much fun. Everybody grinned and did it all over and over again.
