A Different Animal and the Same Beast?

[For those who got the title, mamba supremacy]

As the smoke cleared, two red lights appeared. But they couldn't be the zombie leader's eyes. They simply couldn't. 

They were positioned much higher than the zombie leader, even after the transformation. But as the smoke cleared even further, Jake just kept looking up. 

"A second transformation? You have got to be kidding me. How is this even possible? The first transformation clearly doesn't even have a time limit and he is already on his second transformation? How can I hope to match that?" Jake muttered.

What was even more terrifying, was that the health bar that they had just seen was different now. The yellow was gone, replaced with a very lush green. 

All the attacks later, one transformation undid all of the effort that Jake and the other two had put in. 

The zombie leader completely healed, and was probably stronger than ever now.
