The Lighthouse That Hated Polka

Silas Grumbles, a lighthouse keeper, discovers his lighthouse, Beacon, is sentient and despises his polka music, preferring sea shanties. Beacon often interferes with the light when Silas plays polka. During a thick fog, Silas plays a shanty at Beacon's insistence, successfully guiding a lost fishing boat to safety, proving the lighthouse's musical taste has its merits.
