Plantera

Plantera is a Hardmode boss names after a band called Pantera. It has alot of bugs and attacks, and only is available when the 3 mechanical bosses have been defeated.
When they are dead, a message comes saying "The Jungle is growing restless" and Plantera will spawn. Plantera has two forms, one where it uses range, the other just attacking directly. It also uses the hooks to attack you, and clinging onto surfaces and following after the player. On the first form, its shoots seeds and green poison seeds, or sometimes shoots thorn balls. When it comes down to the second stage, lower than half its health, it starts making "Tentacles". Or it shoots out spores that do 70 damage.
