Ok here is a list of towers and upgrades that can do that:

Dart Monkey: 4|x

Boomerang Thrower: 4|2

Ninja: x|3

Sniper: 1|2 and up

Ice Tower: With tier 4 specialty (only mobile/deluxe)

Monkey Buccanneer: x|3

Monkey Ace: x|2 (not recommended because pinapples only pop the lead layer and the attacks can't aim)

Super Monkey: 4|x (by the time you get it, round 59 would have already passed)

Monkey Apprentice: x|2 (one of my #1 choices)

Mortar: x|3 (another one of my top choices)

Dartling Gun: x|2

Spike Factory: 2|x

Monkey Engineer: 3|x and up (and or get tier 3 specialty building and up)

Heli Pilot: 3|2

Monkey Sub: 3|x (removes camo but doesn't pop it without 4|x upgrade)

And finally:

Monkey Village: x|2 (gives camo detection to all towers within range; x|3 allows towers to pop all types of bloons)

I usually use Monkey Subs (on mobile), Mortars (they remove camos and burny stuff is awesome anyways), and Apprentices (they can pop camo leads pretty cheaply). You can use any of the towers above but those are my choices.
