Monkey Knowledge Packs

 are items in Bloons Monkey City. They can be obtained by capturing Tiles, opening Treasure Chests, game events (such as Festival of Bloonstones) or from Contested Territory milestones and occupation. These special packages contain Cards which give XP to a Monkey Knowledge Book.

This is also available on mobile, being soft-released for Android on September 17, 2015 and fully released for iOS on September 21, 2015.

Obtaining Monkey Knowledge Packs
To get Monkey Knowledge Packs the player's city must be at least Level 12. They can be obtained in both cities. On mobile, only Monkey Knowledge Packs can be obtained by tiles, Contested Territory, or purchasing it with real life currency.

Tiles
There is a 33% chance of obtaining one common Monkey Knowledge Pack from completing a normal tile. Neither NLL nor Hardcore mode will affect this chance. During the Monkey Knowledge Madness event, the chance is boosted to 100%. During a Monkey Teams event that gives Knowledge Packs, you can gain another Pack in addition to the one earned by normal means or through the Monkey Knowledge madness event.

Bloon Beacon
When a player captures a Bloon Beacon tile, you will always obtain a Monkey Knowledge Pack. You can still obtain a normal Monkey Knowledge Pack from capturing tiles in addition to the forced Knowledge Pack. When certain events are active such as Monkey Teams or Monkey Knowledge Madness that give a Knowledge Pack upon completion of a tile and complying with the event's rules, you can gain an additional Knowledge Pack. A Bloon Beacon Tile only comes once every six hours but you can get one instantly if you pay 50.

 * Treasure chests have a 10% chance to give a Ancient Monkey Knowledge Pack.

Wildcard
A Wildcard has the same chance to occur as all other upgrades. It can be used to give XP to the Monkey Knowledge Book of your choosing. They have the same chance to appear as any other card, and are always granted in Wild Card Packs.

Upgrades that may prevent certain strategies

 * Boomerang: Increased projectile hit area/speed can prevent certain tactics from working.
 * Sniper: Increased layer damage can hinder supply drop farming.
 * Apprentices/Mortar Towers: Regrow removal can harm supply drop farming (although you could aim the mortar away from track, and the apprentice seems to still regrow farm).
 * Super Monkey: Increased range can harm the players ability to place multiple temples close to each other (but you can only place up to six temples anyway).
 * Ice Monkey: Zebra/white popping could harm supply drop farming if used as a regrow loop booster (especially as an Arctic Wind, although you could use Glue Hose).
 * Most towers & Monkey Tycoon: Discounts on base cost & upgrades may make more towers necessary for temple sacrifices.
 * Monkey Buccaneer: the +1 grape from Grape Shot attack apparently causes a much higher miss rate for a single x/1+ Monkey Buccaneer on curved paths when attacking loosely packed bloons. It works better with the extra grape on straight lines, though (Grape follows the dart, so two layers at a time).

Trivia

 * It's possible to earn six Monkey Knowledge Packs on a single tile. To do this you have to have a Bloon Beacon spawn on a Treasure Chest (which have a chance of giving both a regular and ancient pack together), have a Monkey Teams event that gives Knowledge Packs, and get lucky and have a normally obtained Knowledge Pack be obtained as well. You can get a sixth one with Mini-Land-Grab.
 * The monkey's appearance on rare and legendary Activated Ability Monkey Knowledge cards is a reference to Super Saiyans from the Dragon Ball manga and anime series.
 * Regrow removal from mortar works only for bloons it can pop (so no zebra/black regrow removal).
 * All Common cards associated with towers have images of the unupgraded towers.
 * All Uncommon cards associated with towers have images of either one of their first- or second-tier upgrades.
 * All Rare cards associated with towers have images of either one of their third-tier upgrades. (The only exceptions are the Tack Shooter, which gives a picture of the Even Faster Shooting upgrade, and the Monkey Ace, which gives the Spy Plane artwork)
 * All Legendary cards associated with towers have images of either one of their fourth-tier upgrades.
 * The BMC Mobile Monkey Knowledge Cards are always the same across every card.
 * All cards associated with towers are at the unupgraded stage.
 * The Wild Card is always the purple jester.
 * The Bloon Sabotage Card is always the doodled Red Bloon.
 * The Monkey Tycoon Card is always the Monopoly Monkey displaying flying dollar bills.
 * The Activated Ability Card is always the red-banded monkey powering up a red flame.
 * In BMC Mobile, if a player receives a Wild Card, the player may hold it until they decide to go to the Monkey Knowledge Books to drag a tower of that player's choice.
