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. Sadly, this is not properly implemented into the Nintendo Switch version of terraria, having the item not work as the cellphone, magic conch, or demon conch.

Trivia

 * The tooltip is both a reference to the "shell" part of the item, regarding the belief one can vaguely hear the ocean if you hold a shell up to your ear, and the "phone" part of the item, regarding a common type of scam call, where the person being called is falsely informed about their car's extended warranty.
 * Unlike the PDA and Cell Phone, the Shellphone folds in half. This type of phone is commonly referred to as a "clamshell", thus the name is also a pun.
