The series explains that because Boota has spent so much time with the super-Spiral Powered Simon, he over time absorbed some of the spiral energy, which he expelled in a burst of will that made him temporarily human. But could this energy stunt his growth and/or prevent his aging? Simon and other humans have way more spiral energy, but HE ages like crazy.
So, what do you think? Is Boota just the victim of spiral energy radiation? Or is he something other than an average molepig?
