* HeyItsThatSound:
** The sound for unlocking an achievement is the same sound used in [[VideoGame/{{Peggle}} Peggle]] when you get the all pegs cleared ribbon.
** The collection of gems in the first game is also used for VideoGame/{{Bejeweled}}'s gem matching and VideoGame/{{Insaniquarium}}'s own gem collecting.
* ImageSource
** BucketHelmet
** InsaneProprietor
** SummonBackupDancers
* KeepCirculatingTheTapes: The original version of the game with the Michael Jackson sprites for the dancing zombie isn't the easiest to get ahold of these days. It ha snot been sold since the change, meaning your only chance to obtain that version is to either hope you can buy a used physical copy made before then, or find a torrent of that specific version.
* LetsPlay: There's one by Daneboe on his [=SuperBoeBros=] channel. There's also one by LetsPlay/NintendoCapriSun and another by [[LetsPlay/McGammar Boltage McGammar]].
* NoExportForYou
** Prior to December 14, 2011, if you own an Android device and live outside of the US or Canada, you can't have [=PvZ=] on Android since the game was exclusively available to the Amazon App Store, which only sells within the US and Canada. The trope was finally averted and made available over the regular Android Market worldwide on December 14, 2011.
** Oh, and if you own an XBox360 but live in a country with no XBox Live support, no [=PvZ=] XBox for you!
* TropeNamer: For SummonBackupDancers.
* ViralMarketing: The [[http://www.youtube.com/watch?v=0N1_0SUGlDQ music video]] (caution: EarWorm!) and various videos of [[http://www.youtube.com/watch?v=98v7Jq6IFrE zombie cosplayers]] on Youtube.
* TheWikiRule: [[http://plantsvszombies.wikia.com/wiki/ Here.]]
* WhatCouldHaveBeen: Quite a lot, actually.
** The game was planned to be a sequel to one of Popcap's older games ''VideoGame/{{Insaniquarium}}''.
** Several other names were planned for the game, such as "Lawn of the Dead" and "Mr. Toad's Wild Lawn".
** There was originally an ice level for the game. [[DummiedOut It is still in the game]], but nothing like what it was originally like.
** Going into the Lawnstrings folder reveals there were zombies called "Dog Walking Zombie" and "Propeller Zombie".
* WorkingTitle: [[DawnOfTheDead Lawn Of The Dead]].
