—Description of Portal Combat in Crazy Dave's Twiddydinkies |
Portal Combat is a Night mini-game in Plants vs. Zombies, Plants vs. Zombies: Journey to the West, and Plants vs. Zombies: Great Wall Edition. It is a conveyor-belt level. Also, like with most Night mini-games, the lawn does not spawn graves.
As the mini-games special gimmick, there are two pairs of connected portals, which act like environment modifiers. Zombies and projectiles enter portals upon contact, then immediately exit through the other portal identical to the one they entered.
Origins[]
The name "Portal Combat" is a pun based on the video game series Mortal Kombat. The white circular portal is a reference to the latter game series.
It can be also based on the popular game series under the name Portal, given the design of the portals.

Strategies[]
The player should be careful of the portals, but not base their entire defense around them, as they will frequently shift positions. It is a good idea to get a Cactus in every lane as fast as possible, although it is a good idea to save up at least one in the conveyor belt, in case a Balloon Zombie comes in a lane where there is nothing to stop it. Cactus is best placed at the very back of the lawn as well since portals can often end up transporting zombies to the very front of your house. Another good idea is to save up the Cherry Bombs whenever they appear and only use them when you have to (e.g. on Football Zombies, or if a portal appears in the back, behind most of the player's plants). Use Torchwoods wisely, as they do not work on Cacti, and place Wall-nuts in front of particularly vulnerable portals. If a portal is too close to the left end of the lawn, try planting Wall-nuts or any other defensive plants to stop the zombies from entering the house. A good idea is to build a solid defense that would work in any level, then watch the portals and be ready to use Cherry Bomb or Wall-nut on zombies in troublesome locations, always keep at least one of each of those plants in your conveyor belt for emergencies.

Trivia[]
- The first portal relocation occurs 90 seconds after the game begins. After that, the portals relocate every 60 seconds.

The flaming peas are trapped by the portals. Note that the "Trickedout", "Future," "Mustache", "Dance", and "Daisy" codes were entered during gameplay.
- Occasionally, portals may appear in positions where, with the same set of portals in a single row, zombies may not be able to walk on a few squares and any projectiles that were fired (or less likely, zombies) before the portals switched may be trapped in an endless circuit, until the portals move away.
- The achievement No Fungus Among Us cannot be achieved in this level, most likely because all the plants available in this mini-game are not mushrooms.
- When a Lawn Mower heads towards a portal, it will teleport to the other portal.
- If a Cherry Bomb is planted horizontally adjacent to a portal, there is an occasional glitch where the explosion will go through the portal. If this glitch occurs, the explosion radius will follow the normal rules for passing through portals, but only on the square directly next to the other portal.
- Along with Zombiquarium and Beghouled Twist, this level is in a mini-game pack for purchase instead of being in the normal mini-games section in the iPad version.
- This is the only level in which the Zombie Yeti can enter the player's house and eat the player's brains or modify the Lawn Mowers without hacking.
- A glitch in the iPhone and iPad version makes the game crash when the first portal is relocated and the bug wasn't fixed since 2016.
- This is the only mini-game to feature Balloon Zombie.
- This excludes the hidden mini-games Air Raid PC and High Gravity, both of which have the Balloon Zombie.
- The Portal concept was used again in Plants vs. Zombies 2, although it was only used to send any time-variant zombies to the present in Modern Day.
- Plants that are not present in Portal Combat are not programmed to shoot through the portals.
- The following projectiles still go through the portals: all peas except for the left peas of Split Pea, frozen peas, and spores of Scaredy-shroom.
- The following projectiles don't go through the portals: the left peas of Split Pea, spores of Puff-shroom and Sea-shroom, stars, fumes, spikes of Cattail, and all lobbed projectiles.
