The frog is an amphibian. It's slippery and can get away from you easily. If it does, you can always try to chase it but you likely won't catch it since it'll head for the deep water in a pond to try to get away from you. YOu could theoretically jump into the pond, and chase after it but opening your eyes underwater in a pond might lead to an eye infection. Then, you'd be in real big trouble.
