Let's say the last kill is to gain fire breathing and he gets to 50ft from the previous kills. But he didn't plan on the last one he needed to kill being on the same mission and also one kill away. It becomes a super Woggle vs super Woggle. The battle rampages across Oz. There is a scene of utter chaos and gore in a munchkin village as they throw munchkins at each other as weapons in ever increasing numbers. Little munchkin arms and legs are laying everywhere. They even eat some of the munchkins to keep up their strength.
They fall into a portal to Genoma during an intense fight and right into the talking tree forest. They rip the trees out of the ground, roots and all, and start using them as staff weapons in a badass martial arts fight scene. The trees are killed from all the hitting and eventually thrown down after they break apart. Cue that sad Sarah McLachlan song from the ASPCA ad with a shot of the trees on the ground with sap running from their mouths and eyes. Slowly of course, because it's sap.
<insert more fight scenes>
Eventually, one of them gets the upper hand and kills the other. As soon as the losing Woggle breathes his last, the winner breathes fire and cremates the body. He then losses consciousness and has a vision. The vision is of the wicked witch of the west (who is secretly orchestrating this whole thing in spirit form). She tells him his evolution has just begun. There are more powers to obtain.
Got yourself a trilogy there.
Booooring. Our version is better.
