Electric Skeleton Piggy Bank

The Electric Skeleton Piggy Bank (often called the "Grinding Skeleton" or "Ghost Money Box") is a popular animated novelty that turns saving money into a spooky performance. When you place a coin on the designated tray, the animatronic skeleton "comes to life"—it typically features glowing red eyes, eerie sound effects or music, and a mechanical movement where the skeleton appears to "grind" or snatch the coin into the storage box below.
