Ivy

Ivy is a novelty instrument dropped by the Steampunker if she is named Whitney when killed. When used, the player strums a chord depending on how far the cursor is from the player.

Trivia

 * In order from closest to player, to furthest away, the chords played are as follows: A Minor - G Major - E Major - D Major - C Major - F Major.
 * The Steampunker's name is a reference to Whitney "Cenx" Spinks, the lead developer of Terraria and wife of Redigit.
 * This is one of only two items which are dropped by NPCs with special names, the other being the Green Cap dropped by a Guide named Andrew.
 * The tooltip may reference the Dead Man's Chest, which often contains a sweater of the same name.
