Hedgehog
Hedgehogs inhabit Europe, Asia, Africa, and have been introduced to New Zealand. Seventeen species exist across these continents, adapting to environments from Mediterranean scrubland to suburban gardens. However, they notably do not exist in the Americas or Australia, limiting their global presence to roughly half the world's habitable landmass. Their nocturnal nature further restricts public encounters.
Pikachu
Pikachu exists wherever electricity and screens converge—which in the modern era means essentially everywhere. The character is accessible in over one hundred countries through games, streaming services, and merchandise distribution networks. Pokemon GO, featuring Pikachu prominently, was downloaded over one billion times within three years of release. The creature effectively exists simultaneously across the entire connected world.
VERDICT
Physical geography cannot compete with digital omnipresence. While hedgehogs remain constrained by continental boundaries and nocturnal schedules, Pikachu manifests wherever humanity has internet access.
