How to use Monkey Intelligence Bureau

Monkey Intelligence Bureau (MIB) makes every attack from towers in range deal Normal-type damage, which means they can damage every Bloon type regardless of immunities: Lead, Black, White, Purple, Frozen and so on. Some towers that normally cannot target a property can now target it too. Effects that only work on specific damage types, such as Sharpening Stone, still use the original type.

When to buy it

MIB is a clean, permanent fix for damage type problems:

  • Towers with several weaknesses, such as a Spectre, become fully effective.
  • It removes the need to plan around Purple or Lead in the late game.
  • Two Monkey Commerce Villages nearby make it cheaper, a common CHIMPS trick.

The usual crosspaths are 2-3-0 for Jungle Drums or 0-3-2 for upgrade discounts.

Cheaper supports often do more for less: Glue Strike and Embrittlement solve damage type issues while adding a debuff, and Heroes like Gwendolin or Striker Jones help specific tower types. MIB is the pick when you want guaranteed, always-on coverage.

Is it worth it?

Yes for many CHIMPS defenses that mix tower types, especially late game. If your defense already deals Normal or Plasma damage, skip it.

Frequently asked questions

Does MIB give Camo detection?

Yes. It includes Radar Scanner, so towers in range also see Camo.

How much does Monkey Intelligence Bureau cost?

$7,500 on Medium. The page shows the price on every difficulty.

Does MIB help with DDTs?

Yes. Towers in range can damage the Lead and Black properties of DDTs and also see their Camo.
