Chip's n' Watermelon Defense.

In the 2000s, humanity wiped itself out with nuclear war, leaving Earth in ruin. Radiation and kinetic energy mutated several bags of chips into sentient beings. Roaming the devastated world, they discovered a horrifying truth: Earth’s core had been transferred into a single watermelon at the planet’s center. This watermelon must be protected, for its destruction could trigger total annihilation. The Chip Nation swore to defend it. From another dimension, energy-hungry invaders sought to destroy the watermelon, drain Earth’s remaining power, and leave nothing but dust. But the chips would not let their world be consumed. Declaring war, they stood against these invaders, igniting a full-scale interdimensional conflict to save their planet and the precious core within the watermelon.
