Medulla Nebula is a galactic uncommon zombie environment card in Plants vs. Zombies Heroes, and a member of the PvZH Brainy IconBrainy class. It costs 3BrainPvZH to play, and its ability gives the zombie hero +2BrainPvZH when a zombie is played in it, but only for the turn that zombie is played.


Its name is a combination of "medulla" (a short term for "medulla oblongata"), the lower half of the brainstem that is on top of the spinal cord, and "nebula," an interstellar cloud of dust, hydrogen, helium and other ionized gases.


  • Class: Brainy
  • Tribe: Gourmet Environment
  • Ability: When you play a Zombie here, you get +2BrainPvZH this turn.
  • Set - Rarity: Galactic - Uncommon

This is a powerful environment that allows the zombie hero to earn more brains whatever zombie you play here. You can play a zombie that costs 1BrainPvZH in that environment which not only gives you a refund, but also additional brains to play a card that's 1BrainPvZH more than usual. It is also useful to play high-cost zombies in this environment to earn additional brains to play tricks like Rocket Science to destroy stronger plants that are played that turn.

Flag Zombie can add up to the profit that you can already get by playing a zombie that costs 1-2BrainPvZH on this environment, due to the reduced costs. By playing Flag Zombie before or while this environment is being played, you can essentially get 2BrainPvZH for free if a zombie that normally costs 1BrainPvZH is played in this environment, and also play powerful cards even earlier than just having Medulla Nebula active alone. However, only Rustbolt can do this normally.

Even better, playing a Brain Vendor on that environment will reward you a profit of 2BrainPvZH, which will allow you to have 6BrainPvZH on turn 4 (which can increase to 7BrainPvZH if Flag Zombie or Terror-Former 10,000 is played beforehand). allowing you to play powerful cards like Bad Moon Rising that turn. Rustbolt can play Gargologist on the next turn to play a powerful Gargantuar such as Defensive End, and can even play Triplication for free if another Gargologist is on the board, rather than using just Brain Vendor to create a one-time effect, forcing the plant hero has to decide whether to invest in taking down the Gargantuar or destroy the Gargologist while taking a lot of damage. Take note that it does require 2 cards in order to perform this combo so it is a good idea to bring card draw or multiple copies of Brain Vendor and Medulla Nebula.

Professor Brainstorm can use cards like Final Mission, Fireworks Zombie and other, similar cards to clear the lanes, letting you use the environment's ability again. He can use Mystery Egg to earn a profit of +3BrainPvZH when it transforms.


This environment can allow the zombie hero to earn a refund of brains or a better profit of brains, so try to remove this environment if you can. Try to play any of your environments in that same environment to remove it easily. You can also use Banana Peel or Whipvine to move a weak zombie into this environment to prevent the zombie hero from playing any zombie in that environment until that zombie is destroyed.

If Flag Zombie is played before or while this environment is active, destroy it as soon as possible as it can allow the zombie hero to play powerful cards even earlier than normal, especially if he or she plays Brain Vendor in this environment.

If you are a PvZH Smarty IconSmarty hero, and your opponent is saving their brains for the Zombie Tricks phase, Brainana can stop this surge in brains for 1 turn, letting you make a comeback. If a zombie is already played there, you can clog the lane with high-health plants to stall them while not destroying them.




  • Its name was originally going to be Brain Silo.
  • Strangely, in the news section, Medula Nebula was supposed to cost 3BrainPvZH in update 1.16.10, but it still costed 2BrainPvZH in game.
    • However, as of update 1.18.13, this was fixed, and Medulla Nebula now costs 3BrainPvZH.
