Everyone saw the pond in the park. It should be warm now. But the pond was still. Like ice. No birds. No wind. Just silent.

Anna walked close. She said, "Why is the water not moving?" She looked down. Fish were under the water. They moved, but they looked strange.

She touched the water. It was cold. Then she saw slowly: the fish were stuck. The water had a bad smell. Something bad was in the pond.

"Help," Anna said, scared. The pond was not normal. It was like time stopped. And the fish could not swim away.
