Get a upgrade building.

Each tower has its own specific upgrade building,

Heres the list;

Dart monkey = Monkey academy

Tack shooter =  Spike Production Building

Sniper monkey =  Gun training hall

Ninja monkey = ninja dojo

Ice monkey = Cryo Lab

Boomerang monkey = Monkey academy

Glue Gunner = Glue factory

Monkey ace =  Aeronautics Laboratory

Spike factory =  Spike Production Building

Monkey buccanear = Ships Foundry (Note:the base building MUST be placed on water, but the upgrade building can only be placed on land.)

Bomb Shooter/Mortar Monkey =  Ordnance and Munitions Support

Monkey Engineer = Engineering school (haha)

Monkey apprentice =  Apprentice School of Wizardry

Banana Farm =  Micro Agriculture Development Building (Note:it may be confusing how to get the base building.)

Super monkey =  Super Enhancements (WARNING: takes up 2x2 tiles)

There, a full list.
