Can You Beat this SECRET Challenge in BTD6?

Can you beat the Secret Challenge in BTD?
This BTD6 challenge makes us use the New SECRET tower to Win!
The secret Bloons TD 6 tower is the ONLY way to beat this challenge!
But it is not that simple, you must also take down the surrounding bloons that are too much for the secret BTD6 tower to handle!
The following challenge is one of the hardest challenges I have played in a while in Bloons TD 6!
Can you beat round 39 with only $900 and 1500% regrow rate in BTD6?

Thank you to Graham and Paulxd for helping me out with this video!
