So, they cant jump, or have tried and failed. Perhaps the frogs are drowning then, is what you are saying...
As a lifeguard, the first thing you need to do in order to save a panicking drowning victim, you have two choices:
1. Wait for the victim to pass out from their flailing...
2. Punch them in the face to break their shock, and they allow a rescue.
Most prefer the first option, if the panicking victim doesnt realize that you are there to save them.
If it's hot, it's too late. That's the lesson.
