~General~

The World is called Jurassic Marsh.

As expected, it contains 32 levels, with Part 1 containing 16.

Jurassic Marsh Part 1 will have a difficulty of 4. This is speculated to be increased to a 5 once Part 2 arrives.

~New Zombies~

Jurassic Zombie (http://vignette4.wikia.nocookie.net/plantsvszombies/images/1/1a/Dino.png/revision/latest?cb=20151004162309)

Regular beard-having zombie from the unimaginable past.

Jurassic Zombie is NOT primitive. See, he's got a tie and everything.

Jurassic Conehead Zombie (http://vignette1.wikia.nocookie.net/plantsvszombies/images/5/5f/Dino_armor1.png/revision/latest?cb=20151004162310)

Cones, or old leftover horns bundled together with string so that they look sort of like a cone, provide some middling protection.

Jurassic Conehead Zombie is trying to get a jump on the whole "traffic cone" idea. He figures it'll be a HUGE market in about 150 million years.

Jurassic Buckethead Zombie (http://vignette1.wikia.nocookie.net/plantsvszombies/images/c/c9/Dino_armor2.png/revision/latest?cb=20151004162310)

Crude drawings of buckets provide as much protection as the real thing.

The real question, the burning mystery, is: where did he find blue for his paint?

Jurassic Flag Zombie (http://vignette2.wikia.nocookie.net/plantsvszombies/images/e/e4/Dino_flag.png/revision/latest?cb=20151004162310)

Marks the arrival of a huge epochal "wave" of highly anachronistic zombies.

He's not only got a flag, but he's also got a can-do attitude and a fierce hunger for success. Success and brains.

Jurassic Imp (http://vignette2.wikia.nocookie.net/plantsvszombies/images/d/d1/Dino_imp.png/revision/latest?cb=20151103041653)

A weaker, smaller, much more vicious version of the typical Jurassic zombie.

This nasty little nipper can make a serious dent in your defenses if left to his own devious devices.

Jurassic Gargantuar (http://vignette3.wikia.nocookie.net/plantsvszombies/images/d/d2/Dino_gargantuar.png/revision/latest?cb=20151103041652)

Prehistoric provider of Mesozoic malarkey.

Damage: Crushes plants with bone

Special: Launches Jurassic Imp when damaged

Jurassic Gargantuar wonders how there can be zombies millions of years before the advent of humanity. He doesn't let it get in the way of his plant-bashing, though.

Fossilhead Zombie (http://vignette2.wikia.nocookie.net/plantsvszombies/images/b/b2/Dino_armor3.png/revision/latest?cb=20151004162310)

Fossil skulls not only provide a huge amount of damage absorption, but are also extremely classy.

Toughness: Machined

Speed: Basic

Contrary to his name, Jurassic Fossilhead's fossil head isn't actually a fossil. That skull's maybe a week and a half old, tops.

Note: This zombie works exactly like Knight Zombie save for the Magnet-shroom weakness. First appears on Day 1.

Bully Zombie (internally referred to as dino_bully)

Nothing is known about this zombie yet. It appears to be in development, but it can interact with dinosaurs. Most likely a Part 2 zombie.

~New Plants~

Grapeshot (http://vignette1.wikia.nocookie.net/plantsvszombies/images/e/ed/HD_Grapeshot.png/revision/latest?cb=20150926063431)

Grapeshots explode and scatter bouncing projectiles in eight directions.

Sun Cost: 150

"Spa-BOOM!" enthuses Grapeshot. "You liked that? I got a million of 'em! Wa-POW! Buh-BLAM! Za-... um... Ker-... hmmm... Okay, I guess I've only got the three

Usage: Single use, instant

Premium Plant for Part 1. Costs $6.99.

Seed Packet: http://vignette3.wikia.nocookie.net/plantsvszombies/images/7/70/Grapeshot_New_Premium_Seed_Packet.png/revision/latest?cb=20151005034602

Primal Peashooter

Sun cost: 175

Recharge: Fast

Primal Peashooters shoot heavy stunning peas at zombies.

Special: Primal Peas occasionally knock zombies back

Primal Peashooter may be primitive, but that doesn't stop him from enrolling and excelling in several software development correspondence courses.

Unlocked after Day 1.

Seed Packet: http://vignette3.wikia.nocookie.net/plantsvszombies/images/1/14/Primal_Peashooter_Jurassic_Marsh_Seed_Packet.png/revision/latest?cb=20151031033936

Primal Wall-nut

Sun cost: 75

Recharge: Fast

Primal Wall-nuts cost a bit more than typical Wall-nuts, but they can be planted much more quickly.

"Grunt," explains Primal Wall-nut. "Grunt oog grunt-grunt," he goes on to say. "Ook-urg grunty grunt grunt," he concludes. A nut of many opinions, is Primal Wall-nut.

Unlocked after Day 4.

Seed Packet: http://vignette1.wikia.nocookie.net/plantsvszombies/images/a/aa/Primal_Wall-nut_Jurassic_Marsh_Seed_Packet.png/revision/latest?cb=20151031033937

Perfume-shroom

Sun Cost: 150

Recharge: Slow (The same as Gold Leaf's)

Perfume-shrooms enchant dinosaurs and charm them into working against the zombies.

Usage: affects all dinosaurs in a lane

Perfume-shrooms emit a pure, concentrated mist of aerosolized love.

Unlocked after Day 8.

Seed Packet: http://vignette2.wikia.nocookie.net/plantsvszombies/images/7/74/Perfume-shroom_Jurassic_Marsh_Seed_Packet.png/revision/latest?cb=20151031033937

Since no other world contains dinosaurs, Perfume-shroom is exclusive to Jurassic Marsh.

Cold Snapdragon (http://vignette2.wikia.nocookie.net/plantsvszombies/images/8/88/Cold_Snapdragon.png/revision/latest?cb=20151028180359)

Sun Cost: 150

Recharge: Unknown

Cold Snapdragons breathe an icy mist into 6 adjacent tiles.

Area: Slows and damages zombies in the 6 tiles in front of it

Cold Snapdragon gets chilly when anyone brings up his cousin Snapdragon. "It happened a long time ago, and I'd really rather not discuss it," he says. Yikes.

Seed Packet: http://vignette3.wikia.nocookie.net/plantsvszombies/images/a/a8/Cold_Snapdragon_New_Premium_Seed_Packet.png/revision/latest?cb=20151031033938

Premium Plant for Part 2. Costs real money. Cost unknown but presumed to be $6.99.

Primal Sunflower

Sun Production: Large Suns (assumed to be 75)

Toughness: Average

Sun Cost: Unknown

Recharge: Unknown

Primal Sunflowers pop out large suns instead of regular ones.

Primal Sunflower is new to all this sun-giving business, so be patient with her. She's an early adopter of the all-you-can-stuff-yourself buffet style of sun production.

Part 2 Plant.

Primal Potato Mine

Usage: Single use, delayed activation

Range: Affects area around it

Sun Cost: Unknown

Recharge: Unknown

Primal Potato Mines take longer to arm than regular Potato Mines, but they do damage over a larger area.

Area: Most likely 3x3

Primal Potato Mine doesn't consider himself to be primal. As far as he's concerned he's state-of-the-art. And who knows? Maybe he is.

Part 2 Plant.

Shrinking Violet

Almost entirely unknown. Seemingly in early development. All that is known about it is that it does something in a 3x3 area and possibly lasts a limited time like Puff-shroom.

Part 2 Plant.

~Dinosaurs~

Dinosaurs are the new gameplay mechanic in Jurassic Marsh. They will not attempt to eat your brain, and Plants cannot attack them, although they can assist the zombies.

There are 3 dinosaurs for Part 1: Velociraptor (introduced on Day 2) Stegosaurus (introduced on Day 6), and Pterodactyl (introduced on Day 8 or Day 9), each with their own abilities.

There are also at least 2 more to be introduced in Part 2: T-Rex and Ankylosaurus.

The Velociraptor walks halfway up the lawn and then turns around. It keeps doing this until it gets bored and then just leaves, unless it encounters a zombie, in which case its uses its feet like a kangaroo and launches the zombies forwards.

The Stegosaurus snares zombies with its tail, then flicks them off.

The Pterodactyl basically just turns a zombie into a Bug Zombie except the bug cannot be killed.

All others have unknown abilities.

~Dialogue~

Day 1:

Penny: Alert, User Dave. My sensors indicate we have moved 153,954,765 years into the past.

Crazy Dave: Yabbers! That's before I was even born!

Penny: Correct. We seem to have landed in some form of Jurassic Marsh.

Crazy Dave: I knew I smelled more oxygen!

Day 2:

Penny: This epoch is known for its unusual lifeforms, User Dave.

Crazy Dave: I know! Gymnosperms, right?

Penny: I was thinking more in terms of saurians, User Dave. Dinosaurs.

Penny: They won't attack us directly and we can't affect them.

Penny: However, they will definitely react to zombies. Be wary!

Day 6:

Crazy Dave: I can feel the ground a-trembling, Penny! More dinos?

Penny: Indeed, User Dave. A herd of stegosaurs approaches.

Penny: My sensors indicate they will snare zombies with their tail, and then flick them off.

Crazy Dave: That's what I would do!

Day 9:

Crazy Dave: Penny! I just remembered how much I love silent letters!

Penny: Coincidentally, User Dave, a flock of pterodactyls is approaching.

Crazy Dave: Pterodactyls? That's ptotally pterrific!

After receiving note:

Crazy Dave: Look, Penny! A fresh star-hunky!

Penny: A meteorite. Curious. My records indicate this should be... bigger.

Crazy Dave: Bigger? Like, super burrito-sized?

Penny: More like super Seattle-sized. I hope history has not gone awry...

Day 16:

Dr. Zomboss: Surrender your brains forthwith, inane time stumblers!

Dr. Zomboss: Else you shall share the fate of these terrible thunder lizards: EXTINCTION!

Crazy Dave: But I don't want to get extincted!

~Achievements~

Dino Sore: Prevent all the dinosaurs in a level from interacting with Danny zombies

Terror Redactyled: Use a Perfume-shroom on a pterodactyl carrying a zombie towards your house

Martial Marsh Master: Unleash the Jurassic Gargantuar
