Unfortunately a mutant race of maple trees with Canadian accents and mounty uniforms killed the race of super turtles with russian accents and viking beards and helmets who came to avenge us all.
Unfortunately they were not invincible against the bazookas the mutant races of maple trees with Canadian accents and mounty uniforms happened to be carrying.
