Juggernaut-o-pult

The Juggernaut-O-Pult looks like a 4/0 dart monkey, except it fires Juggernaut projectiles at hypersonic speed (super monkey rate) ! Its has the range of a super monkey with epic range and it costs $19000/20000/21000 on Easy, Medium and Hard respectively. It can detect camo and a pierce of 100! Path 1:

Extra range ($2000/3000/4000) : Gives the tower an extra 15 pixel range

Bigger Projectiles ($3000/4000/5000) : Makes the projectiles bigger

Solid-Naut ($50000/60000/70000) : Fires a solid stream of Juggernaut projectiles

Path 2:

Smart Projectiles ($1500/2000/2500) : Projectiles seek out bloons and pop them.

Sharper tips ($3000/4000/5000) : All projectiles deal +1 damage

Triple Pult ($30000/35000/40000) : Fires 3 projectiles at once
