Biologically, frog has tendency to change the temperature of his/her skin according to the external temperature.

So, the frog adjusted it's body temperature according to the boiling water.

Water temperature rises, again the frog changes it's body temperature.

Gradually, the water temperature became so high that it couldn't tolerate it anymore.

So, it started doing the only thing it could do- Jump from the pan.

But tragedy happens, the frog died.

**Now, the question is- who killed the frog?**
