If you thought you saw a giant walking banana last night, it's because there was a giant walking banana last night.
Given the species' superior aerodynamic form, threatening pointy bits, and ability to thrive in a harsh equatorial climate, it's worth considering that a mobile and sentient banana might represent the pinnacle of evolution. Note that last night's giant walking banana wasn't the least bit deterred by a powerful thunderstorm, while the humans in the area were compelled to shield themselves with thin sheets of plastic.
I don't know about you, but if last night is a sign of what lies ahead, then I, for one, welcome our new banana overlords.
