Old School (Achievement)

“	Have the Monkey Apprentice, the Sniper Monkey, the Dart Monkey, and the Boomerang Monkey on the map at the same time	”
	^{~ BATTD description}

Old School is a hidden achievement in Bloons Adventure Time TD. It is unlocked when a Dart Monkey, a Boomerang Monkey, a Sniper Monkey, and a Monkey Apprentice are placed together on the map in the same game. It rewards one Uncommon wish orb on completion.

Strategy[]

This achievement requires placing down at least two Common allies, one Rare ally, and one Super Rare ally.
It is advised that newer players hold off from completing this achievement until they are able to get all of the mentioned allies through opening wish orbs due to its lowly reward of an Uncommon orb compared to the Super Rare rarity of the Monkey Apprentice. The player can also buy the allies from Daily Deals, but the gems can be spent on much more valuable and powerful items in the long term, such as the Thought Cannon Wand.

There are also other monkey allies in BATTD, namely Ice Monkey, Pirate Crew, Elf Monkey, Squadron (if considering the monkey pilot), Super Fans, Dr Monkey, Wizard Lord, COBRA, Technological Terror, and Monkey Farmer. However, none of them contribute to this achievement in any way.
