Tips and tricksEdit

Captain Cassie can be a good mid-game tower and for deal a horde of bloons.

When you got her at lvl 7 her MOAB Takedown make her also medium for late game as she will help also in grouped bloons.

You're deciding which you will use, Captain Cassie or Commander Cassie? Captain Cassie is good at first 40 rounds of the game but Commander Cassie at any round better for example she solos a normal MOABs with triple barrel only. The only weakness of Captain cassie is that she's weak against MOAB-class bloons.

The privater works also with Warrior Bubblegum; if you want to replace princess one with warrior is bad idea because you lose the regal presence.

Update HistoryEdit


  • BuffMOAB Takedown price increased from $2500 to $3000, damage increased from 2000 + 1350 per crew to 2500 + 1500 per crew



  • Cassie calling MOAB Class Bloons "MOAB-y Dick" is a play on Moby Dick, an 1851 novel.
  • As described above, Cassie has a hidden Treasure Hunter upgrade that isn't revealed on her upgrade tree until specific conditions are met. This upgrade only reveals itself during these conditions, and does not stay permanently revealed once purchased.
    • Upon purchasing this upgrade, the player is awarded with a hidden achievement of the same name.
    • Though, when the requirements are met, it will show on the upgrade tree.
