Spooky Bed in Animal Crossing (GameCube): No Cheat — Seasonal Only

No cheat code unlocks the Spooky Bed. It's a seasonal item obtainable only during October (Halloween):

1. Wait for October 1–31.
2. Talk to villagers on Halloween — they may gift it.
3. Check Nook's Cranny daily (stock/price varies).
4. Shoot down balloons — random chance.

It's rare; patience and luck required. No off-season acquisition method exists.
