Peninsula/Strategies

Peninsula is a very difficult course, even among advanced tracks. The extreme lack of land near the track makes hero placement difficult and throws off standard openings. The watery layout would be perfect for Monkey Subs, but the large landmass makes it impossible for subs to cover more than 2/3 of the track, and subs would be firing behind the bloons part of the time, which is not ideal. Subs are a powerful addition in the early game, however.

Early game
One technique that works (with a bit of targetting micro on the sniper between Strong and First) consistently is the following:

-Three Dart Monkeys on the clear island, one set on 'Last'

-A 0-0-0 Monkey Sub at the first big bend, set on Strong

-A 1-0-1 Sniper Monkey on the cliff set on Strong

-Upgrade sub to 0-0-1

-Upgrade sniper to 2-0-1

-Clear upper left island

-Place 1-0-1 Ninja

-Place Hero

Alternatively, you can omit the sniper and upgrade one dart monkey to 0-1-3, as in this video.

Mid/Late Game
There's not enough room for a lot of land units, the course is too short for many Heli Pilot strategies and/or Monkey Sub strategies, so you'll have to improvise. One option is to use a 0-3-1 or 0-3-2 Ice Monkey to increase the landmass. If you used the opening above, and picked Obyn, you can use this technique for the classic 4-0-2 Ninja Monkey, 3-0-2 Super Monkey, 4-0-2 Alchemist and 0-0-2 Monkey Village setup. Adding another village for M.I.B. should take you to the mid-80s, letting you save up for Avatar of Wrath or another powerful monkey.

This technique is a little more tricky on this map due to the slowdown caused by placing the ice monkey. You can bolster your defenses in the early rounds by upgrading a sub to 2-0-3 and boosting it with with a 3-0-2 Alchemist, such as in the lower-left corner.
