Squirrel

Squirrel was a removed minigame that was centered around capturing squirrels.

Strange Text
If files are extracted from Plants vs Zombies, strange texts can be discovered that never made it into the game. A few of them mentioned 'squirrels':

"[SQUIRRELS] Squirrels"

"[ADVICE_SQUIRRELS_ONE_LEFT] {COUNT} more squirrel to go!

"[ADVICE_SQUIRRELS_LEFT] {COUNT} more squirrels to go!"

"[ADVICE_SQUIRREL_ZOMBIE] Oh no! Find all the squirrels before the zombie makes it to your house!"

It is unknown if this would have been voiced by Crazy Dave, or it would possibly just appear as guidance text.

Trivia

 * It is possible to play Squirrels by using a cheat engine.
 * It is unknown if the Squirrels would have been based on a certain species, or just a generic animal.
