Shellphone

The Shellphone is a post-Skeletron informational item that combines the function of Cell Phone, Magic Conch, and Demon Conch. The player can press to cycle through four teleport locations: World Spawn, Ocean, Underworld, and Spawn Point.

Trivia

 * The tooltip is a direct reference to a common scam call, where the person being called is informed about their car's extended warranty, and asks them to 'renew' it.
