Night guys

In a pixel art crossover, a pink Kirby and a yellow Pac-Man character fight on a tropical island with palm trees and a rainbow, where Pac-Man punches Kirby into the air and they collide mid-air, followed by a transition to a scene with a spiky-haired character in a blue jacket running across a grassy field, then a bright flash reveals the letters "K.O." in a colorful, pixelated font.
