Baby Mosaic

Baby Picasso is an Extreme Difficulty track for BTD*any random number*, based off the cubist style of the artist Pablo Picasso.

Description
There are exactly 20 paths on this track. All the entries are located on the top and the left, and all exits are located on the bottom and right.

The curious thing about the track is that the bloons do not come directly from all entries at the same time. One random path is chosen every 2 rounds, but in the first round the bloons will come out normally, and in the second one the bloons will go backwards (ie from the exit to the start).

The track is so hard, that the player is given $ 2000 at the beginning of the game instead of $ 650. However, you need to pay 60MM to play it, and no saves.

Some strategies

 * The best way to start is with Dart Monkeys scattered all over the place. Then, upgrade them to 2-0 and buy Monkey Buccaneers in different blue spaces. Grape Shot upgrade is also useful.
 * 2-2 Monkey Apprentices may be useful in Rounds 20-40.
 * Super Monkeys are more effictive with Epic Range upgrade.
 * Dartling Guns are the best option for advanced rounds like 46.
 * The hardest paths are the ones from the lower-left corner and the upper right corner, which are ridiculously short. 4-2 Glue Gunners are required for beat normal bloons in there, and special abilities like MOAB Takedown or Ground Zero for MOAB Class Bloons.
