Sneaky Bloons

Sneaky Bloons are a bloon property that lets it go through shortcuts (if there are any), and go invisible for a few seconds. They will appear in SpongeTechX's upcoming Bloons Tower Defense game, Bloons Tower Defense Rampage. These types of bloons are easy to miss if your monkey doesn't have good range. If the bloon goes invisible, it can still be popped. You have to get a sniper monkey or super monkey to detect it while invisible, or you could wait until it is visible again. But, by then, it may already be too late.
