Shroomtera

"The mushrooms grow restless..."

This is a hard mode boss spawned by breaking a shroom bulb in a jungle that is converted into a mushroom biome. it looks like plantera, except with a giant fungi bulb head, and fungi bulb legs. It is technically the mushroom plantera, only her second stage attacks are faster. It drops and acts like plantera, but summoning it and plantera at the same time will kill the player. Unlike Plantera, however, it doesn't have a second stage, although it becomes enraged when leaving the underground mushroom biome.

Stage One
When Shroomtera spawns, she will act much like plantera. as well as firing bulbs and thorns, she spits out shroom balls that act like plantera's thorn balls.

Stage Two
When Shroomtera drops to 15,000 health, she becomes a bit larger, and fires bulbs, thorns, balls at a incredibly fast rate, equal to double plantera's speed. also her grapplers become fungi bulbs with claws, which deal damage but can be defeated, with 789 health. if all her grapplers are killed, they respawn again. Note that each one drops 85 silver coins.

Stage Three
Shroomtera is special because she has stage three, being the only boss (except duke fishron) to have this amount. It is no different from stage two, except she fires rains of shroom spores, similar to those of the giant fungi bulb's fungi spores.

Drops and Aftermath
When Shroomtera is defeated, the message "Screams are echoing from the dungeon..." appear, and the dungeon will host the post plantera monsters. also, golem can be defeated.
