Monkey Mastery (BTDB2)

Monkey Mastery is a cosmetic system for individual monkeys in Bloons TD Battles 2. Monkey Mastery is unlocked when all upgrades of a certain Monkey have been unlocked. Each Monkey in the game has nine purchasable cosmetics, which do not have to be purchased in order. These cosmetics could be Monkey-specific, such as unique animations, or a themed piece of Bling, like Bloon decals and emotes.

Monkey Mastery is accessible on the third tab of an individual monkey's upgrade information page.

Trivia

 * The Ice Monkey's "Captain Scott" avatar icon is a reference to Captain Robert Falcon Scott, who led expeditions to the Arctic.
 * This also explains the Ice Monkey's default monkey name, Scott.
 * The Monkey Ace's "Do A Barrel Roll!" mastery upgrade is a reference to the famous quote from the game Star Fox 64.
 * Its description, "Like it's 1997.", also refers to the game's release date.
 * The Dartling Gunner's "Foam Darts" mastery upgrade and its description is a reference to the popular kids weapon franchise Nerf.
 * The Monkey Village's "M.I.B." mastery upgrade and description refrences the Men In Black franchise, specifically their neuralyzers, which wipe the memory of people nearby when used.
 * The Monkey Signal emote is a reference to the Batman signal.
 * Its description "The hero we deserve, not the hero we need" is a reference to the quote used in the movie "The Dark Knight" released in 2008.
 * In the Customization Tab(second from the left), the customization order is: Placement Animation, Sell Animation, Idle Animation, Trail Effects, Weapon Skin.
 * Every tower has exactly 9 customizations, including at least one Placement Animation, Emote, Bloon Decal, Avatar Icon, Custom Names, Sell Animation and Idle Animation.
 * The Bomb Shooter, Ice Monkey, Mortar Monkey, Wizard Monkey, Super Monkey, Monkey Village and Spike Factory are the only towers to not have a weapon skin.
 * The Bomb Shooter, Mortar Monkey, Dartling Gunner are the only towers to have a MOAB-class bloon skin.
 * Respectively, the Bomb Shooter has a MOAB skin, the Dartling Gunner has a BFB skin and the Mortar Monkey has a ZOMG skin.
 * The Wizard Monkey and Super Monkey are the only towers to have 2 idle animations.
 * The Monkey Village and Banana Farm are the only towers to not have a trail effect.
 * The Dartling Gunner is the only tower to not have an idle animation.
 * The Mortar Monkey, Monkey Village and Farm are the only towers to have 2 or more emotes.
 * Among the three, the Monkey Village is the only tower to have 3 emotes.
 * The default name for Banana Farm "Ol'Mcdarty's" is a reference to a children's song Old MacDonald Had a Farm.
 * Ice Monkey's Snowman description "Do you want to build a snowmonkey?" is a reference to the first Frozen movie, albeit as "Do you want to build a snowman?".
 * The context of this reference is when young Anna tries to convince young Elsa to play outside with her, singing the song "Do you want to build a snowman?"; Anna, Elsa's younger sister, wants Elsa to play with her, unaware of Elsa's forced isolation resulted by her ice magic. Fittingly, the Ice Monkey can be considered to have ice magic because he repeatedly claps to create freezing auras.
