Trifunctional

Thin Ice is the forty-eighth level in Bloons Player Pack 1.

Completion
To pop all three bloons, you need to aim for the top, but with little power, in order to pop the bloon on the monkey. Next, pop the bloon using the Rubber Block on the bottom. Finally, pop the bloon on the top by using the rubber block on the top. Note that this may take multiple tries.

Trivia
