1636 Pokemon Fire Red | Squirrels

For context, there are no squirrels in Kanto. Not one. The region boasts electric mice, beavers, psychic foxes, and even living piles of sludge, but the humble squirrel— Sciurus vulgaris —is conspicuously absent. This is a botanical mystery, as Kanto is filled with oak and chestnut trees. Yet, in the 1636th line of the Pokémon species database, a ghost of a creature stirs.

Most historians dismiss this as a sailor’s fever dream. But the code in FireRed tells a different story. 1636 pokemon fire red squirrels

So the next time you hear a rustle in the bushes outside, or see a squirrel bury a nut with frantic, purposeful energy, consider this: it might be hiding an Ember. It might be waiting for the right player to press A at frame 1636. And if you ever manage to catch it? Do not save. Do not trade it. Let it run back into the time-between-frames, where the autumn of 1636 never ends, and the forests of Kanto are still full of fire-colored squirrels. For context, there are no squirrels in Kanto

It began not with a bang, but with a rustle. In the autumn of 2004, while datamining the newly released Pokémon FireRed Version , I stumbled upon a hexadecimal sequence that should not have existed. The address was 0x1636. Within the game’s code, nestled between the cry data for Rattata and the sprite pointers for Spearow, lay a set of 12 unused bytes. When forced to compile, they generated a creature the fandom would later call the “FireRed Squirrel.” This is a botanical mystery, as Kanto is

Why does it matter? Because every time you play FireRed and walk through the tall grass of Route 1, the game’s RNG cycles through 1,500 possible encounter slots. Slot 1636 is empty. But for a single frame, the game almost looks there. If you press A at the exact moment the frame hits, the screen will flash orange for a millisecond. That is the FireRed Squirrel. It is not a Pokémon. It is a memory of a memory—a burnt acorn stored in a tree hollow that no longer exists, in a forest that burned down three hundred and seventy years before the first Pokémon game was ever conceived.
