Artwork of the Sub Construction Yard
Sub Construction Yard(or Monkey Sub Bay) is a Specialty Building for the Monkey Sub. It costs 
600 to purchase it and it increases the cost of Ninja Monkeys and their upgrades by 5%. Before it can be purchased, 250,000 Bloons must be popped to unlock this specialty building as the Monkey Sub requires 250,000 pops to unlock. There is number 86 on the building.
Upgrades[]
600 - Reduces tower and upgrade cost by 5%.- 650(600 in BTD5 web) - Increases projectile speed of Monkey Subs by 25%.
- 750(1000 in BTD5 web) - Makes Airburst Darts split into 4 instead of 3.
- 1,300 (BTD5 Mobile only) - Submerged Sub's sonar also shocks Regrowth Bloons into normal bloons.
Tips and Notes[]
- The third tier upgrade can greatly increase your firepower, especially if used next to a Monkey Village with Monkey Fort or if you are only using Monkey Subs.
- The fourth tier upgrade is very helpful for rounds where there are large concentrations of Camo-Regen Bloons, which can help your other towers pop them faster.
