The Monster High version of the iPhone, it's a cell phone that almost each of the characters in the franchise has. An iCoffin itself is mostly just a coffin-shaped cell phone (hence the name "iCoffin"). This phone is the main type of technology in Monster High. Oddly enough, there isn't any other type of phone talked about in the show, while Cleo's Basic doll has a regular cell phone on her leg of her outfit. In "Why Do Ghouls Fall in Love?" every single one of the monsters pulls out an iCoffin when Clawdeen pulls out hers. This probably means that they all have them.
