So this world happens in 1930's on film set! All spooky decorations and stuff! Main gimmick – photo cameras and video cameras. One camera occupies one tile on lawn and there’s usually 3-5 of them. Cameras are indestructible but take damage. Lobbed shots ignores camera, while straight shots are blocked by it. When cameras take some amount of damages, they activate their ability – photo camera takes a picture and stuns all zombies (with the exception of non-actor zombies). Video camera starts to record which speeds up all zombies and their chewing speed for several seconds or until they leave came radius. Radius of cameras is usually 3X3 space in front of them.
Regular trio is presented as some kind of royal family that lives in haunted castle. Imp is actor too,
Zombie ghost “several times undead” - flies through any kind of plant, and haunt a plant that right below him (temporary disables plant, except Ghost Pepper)
Zombie vampire – not only heals himself while eating, but also increases eating speed while doing that (there’s some limit, of course). Garlic damages him instead of healing.
Zombie werewolf – octopi clone. Can pick a normal plant, and carry it to smash next plant! Then picks up it again. He also uses picked plant as shield, so if he picked up a walnut, you will have problems!
Zombie witch – Slowly flies towards your house and throws evil potions on the ground. Potions make ground cursed – you lose extra 50 sun regularly if you have a plant on that tile. Intensify Carrot could help you clean the ground (It won’t take away that extra 50 sun in that case). Can’t throw a potion on tile that has already plant on it.
Mad scientist “Zomboss’s childhood hero” – Kills random plant on his lane with his electric zap from time to time. Lighting reed and Electric blueberry are immune to that.
Zombie mechanic – non-actor zombie. Moves towards one of the cameras an starts fixing if it is photo camera, to prevent taking pictures. Also starts damaging video camera to make it work.
Gargantua - also non-actor zombie. Holds video came in his hand, so every time he smashes something, it speeds up all zombies around him for a moment.
Minigame might be related to fog machines?
Boss: Movie set robot with Zomboss as producer.
Plants: honestly, I don’t see any reason to have extra plants here as we already have possible counters and stuff.
Tesla shroom: protects all plants around it from electric zap and increases speed of lighting reeds and blueberries around him.
Ghost cherry: Haunts everything in 3X3 radius then explodes and damages everything in 1X5 area, like Jalapeno.
