The Grim Adventures of Plants vs. Zombies                                                              
The Grim Adventures of Plants vs. Zombies

is a fan fiction crossover of

The Grim Adventures of Billy & Mandy

& Plants vs. Zombies


When Billy's dad leaves to buy underwear, Billy wears his dad's "lucky pants" despite being told not to. Billy accidentally gets Grim's scythe stuck in the pants, and he tries to get help fixing them before his dad gets home. He calls "Ed, Edd n Eddy's Pesky Problem Fixers", but Billy doesn't have any money, so Eddy tells him to call the Plants from Plants vs. Zombies since "they're cheap."

When they arrive to fix the pants, they find they need 2x4 technoligy, so Sunflower dresses up as Billy to stall Billy's dad, while the rest of the plants take Billy to the Misty veiw park hospital to fix the pants. Jack O Lantern comes to Billy's house to look for revenge on Billy, Mandy, & Grim, and knows that Sunflower is not Billy. Jack captures Sunflower, and tortures her until Sunflower tells Jack everything about Her and the plants.

Meanwhile, the rest of the Plants are takeing Billy to the Misty veiw park hospital, and they get an urgent message from the police that Dr. Zomboss is using a "zombieization machine" to make more zombies into his minions. The Plants reluctantly take Billy on the mission, where he mistakes the zombie machine for a bathroom, fusing him, the lucky pants, Grim's scythe and The zombot head into a being for Dr. Zomboss to controll called the "Zombie Reaper".

Meanwhile, Grim and Mandy come to Billy's house, and mistake Sunflower for Billy. Grim then says that his scythe has been fused with an evil scientist, and Sunflower realizes that he is talking about Dr. Zomboss. The Zombie Reaper begins fusing humans into it

The Plants return to Misty veiw park, where they find Jack disguised as Sunflower Only the Plants know that he's an imposter, but since nobody else does, Jack convinces the mayor they are losing their minds. Soon Jack becomes ruler of Misty veiw park renaming it Jack veiw park. Sunflower, Mandy and Grim arrive at Misty veiw park where Grim finds out that Sunflower isn't Billy, and Jack imprisons them with the other plants.

The Zombie Reaper continues making humans fuse with it, so after escaping, The plants, Mandy and Grim fuse together with the Bone of Barnacles to create a Giant Skeleton Samurai to battle the Zombie Reaper. A giant J.A.C.K.R.O.B.O.T., piloted by Jack and some officers comes into the battle. Jack's robot begins to lose until the plants, Mandy and Grim show up and fight the Zombie Reaper though they begin to lose as well because Billy's dad's lucky pants are impervious to lasers, supernatural energy, and sun.

When the Zombie Reaper is distracted by the Plants,  Mandy and Grim, Jack accidentally fuses himself with the Zombie Reaper, giving him control of it. However, Billy's dad comes, removes the lucky pants and takes them away, being really, really angry that someone is wearing his pants. Without the lucky pants, the Zombie Reaper is defenseless and the Skeleton Samurai finishes it off, freeing the other humans inside it (causeing all the characters to beat up Dr. Zomboss as punishment and revenge for being evil and trapping them inside the Zombie Reaper). Jack is taken away by the plants, but eventually he escapes, vowing revenge, but then gets crushed by a safe, and everything goes back to the way it was, except for Sunflower (who gets dragged away by Harold, believing her to be Billy, to be punished) and Billy (whom tries to pretend to be Sunflower only for everyone to hit him).

References to other shows & gamesEdit

Ed, Edd n Eddy make a short cameo when Billy calls them to fix his problem. Their scam was "Ed's Pesky Problem Fixer".

When the plants arrive at Billy's house, he exclaims, "Hey! You're not the Bejeweled jems!"  Bejeweled is another game by Popcap and the Bejeweled jems are other character that fly out and kill dr. Zomboss when The Zombie Reaper is defeated.

When Jack tortures Sunflower,  Fred Fredburger says "I like TV shows that have talking Sponges", "Sometimes I like TV shows that have talking penguins in a city zoo. And sometimes, I like TV shows that have friendly toy monsters with music, dance, colorful cartoons and simple life lessons that will get you and your children up off the floor to learn and dance along instead of Penguins. But sometimes, I just like dancing penguins.", "I also love shows that have monsters and shows with a teenage robot, and shows with fairies that have magical powers called Winx. And I also love shows that have a boy with flaming hair and his talking dog and two genius sisters who experiments on him. I also enjoy shows about monkeys. I also enjoy shows about monkeys going to camp. I also enjoy shows about imaginary friends." this refers to the other shows; SpongeBob SquarePants, The Penguins of Madagascar, Yo Gabba Gabba!, Happy Feet and it's sequel, Aaahh!! Real Monsters, My Life as a Teenage Robot, Winx Club, Johnny Test, My Gym Partner's a Monkey, Camp Lazlo, and Foster's Home for Imaginary Friends, respectively.

When Jack/The Zombie Reaper has a shotgun pointing at the heroes, he says to them "Say hi to my mother for me. Oh, and Harvey Birdman."  He refers to the superhero-turned lawyer Harvey Birdman

When the Zombie Reaper is assimilating humans, various characters are seen. For example, some girls from both shows are shown arguing over whether hi you girls or Sassycat dolls are better. Also, Mr. Messy is seen being beaten up by Dr. Robotnik as Iron Will comes to the rescue

When Jack gets captured, he says "I would've gotten away with it, too, if it wasn't for you meddling Plants!" parodying a catchphrase from Scooby Doo. It should be noted that the phrase was parodied on Billy and Mandy a few times before.

Billy: Hey can you slow down? This talking at the same time is really hard.

Marigold: OOH! ooh! I want to try talking at the same time too!

Dr. Zomboss: That can be arranged, for an officer can be first to be assimilated by.. THE ZOMBIE REAPER!

Imitater: Wait, start over! I wasn't ready!

Wall-nut: Come on back to the plant-mobile!

((an officer has just been assimilated by the zombie reaper))

Gatling pea: OFFICER!!

Dr. Zomboss: He's only the first one to be assimilated by me.. Soon all humans will assimilate!

Jack-o-lantern: More and more humans are losing their minds and it leads me to believe it is a virus planted by the Zombies.

Crazy Dave: That's horrible! Do you have any idea what we should do?

Jack-o-lantern: Yes, I do, but first there are going to be a few changes around here.

((Zombie Reaper came to Irwin's house))

Irwin: Dude! You're late for the party yo!

Dr. Zomboss: You shall assimilate!

Billy: WAAAIIIT! Can't we have some cake before we assimilactate?

Dr. Zomboss: NO!

Cherry #1: What in the heck is going on around here?! And where is The Mayor?

Jack-o-lantern: he seemed to have caught the same virus as you did, so I had him quarantine in the med lab.

Jack-o-lantern: In the meantime I'll be taking over as supreme commander.

Officer: Yeah! And we get to be Sunflower's personal guards!

Tall-nut: I keep telling ya' all THAT IS NOT SUNFLOWER!!

Jack-o-lantern: You're obviously sicker then I thought and whatever it is you've got, it's spreading, so in order to contain it my first order as the leader is that my name would be referred to as.. Jack-O-lantern.

Fume-Shroom: Jack-O-lantern? That's the craziest name that I-

Grim: It's not a costume! I am the grim reaper, and you have no idea of the power I possess.

Grim(while grumbling under his breath): If you say so.

((The Zombie Reaper assimilating everyone on its path))

Dr. Zomboss: Assimilate! Assimilate!

Billy: Assimila-la-la-la-la-la-la

Dr. Zomboss: Would you stop it! Ugh, I wish I had never assimilated you in the first place!

When Sunflower said "We normally stay away from this town with all of the weird things that happen here." this may have meant that all towns of all cartoons and games is a city.

The Zombie Reaper's phrase "Assimilate" may be a spoof of the Daleks from Doctor Who, who are known for shouting "Exterminate."

"Assimilate" may also be seen as a reference of the Borg from the Star Trek series, who seek total "assimilation" of the universe.

Gladys appears in this,but only as a cameo on a picture frame

Billy too may have control over the reaper as he was the only one able to overcome his/her control before Jack was under Zomboss's control
