Danger!

Danger! is the 33rd level of Bloons. In this level there are 3 5X5 squares with their corners cut off. Inside them there are two Tack Bloons, but when they are popped, they will get the Ice Bloon that will freeze the entire square (this may be the origin of the name Danger!). Popping 30 bloons results in the win.
