More moab class bloons

I love the game so much! The only thing is freeplay gets kind of boring after a while because all there is is red and green moabs and the only way the rounds get harder is by making the moab class bloons faster and by making the rounds insanely long my suggestion is to make a bloon that has 10 times the health of a zomg and holds 10 zomgs inside of it it would only come at round 150 or something and later just to give people doing freeplay motivation to keep going and try to get to round 150 because there is pretty much no point to doing freeplay but there would be if this was added because everybody would want to see a new bloon and you could even make an even stronger bloon than the one I talked about before and have it come starting at round 200 during free play I think that this would not be too hard to do and it would make the game a lot better so plz add this plz
