Plantera

Plantera is a hardmode boss. It is summoned by destroying a pink bulb that grows in the open areas of the Underground Jungle. The pink bulb only spawns after either The Destroyer, Skeletron Prime, or The Twins have been defeated.

Like several other bosses, Plantera has an alternate form when it reaches half health. In this second form, its mouth opens and charges around at the player, moving around somewhat quicker and erratically. When it is defeated for the first time it will always drop a Grenade Launcher with Rocket Is.

Trivia

 * "Plantera" is a parody of the American thrash metal band Pantera. It was named as thus because Pantera is Redigit's girlfriend's favorite band.
 * Plantera also drops "The Axe", which looks similar to the Washburn and Dean electric guitars often used by the late Pantera guitarist Dimebag Darrell.
 * Plantera's boss music also consists of heavy usage of electric guitar, the basis of metal music.
