Optimally, you should go aim to buy the following as well: My general strategy: Add more 3/0 or 2/3 boomerangs, and a 3/0 Bomb Tower.
 * 3/x Bomb Tower (Cluster Bombs)
 * 3/x Boomerang Thrower (Glaive Riccochet)
 * x/2 Spike Factory (increased spike production rate upgrades)
 * More boomerangs
 * Start with a 0/0 Spike Factory near the end and aim to purchase a 2/2 Mortar ASAP
 * Get a Bionic (in a decent position so it loops around the track perfectly, if possible) or a Riccochet otherwise.
 * If Camo leads begin appearing early, you may need to delay the Bionic/Riccochet purchase and get a 2/3 Mortar instead.
 * 2-3 Bionic Boomers set to last in a good position will suffice for stronger, non-MOAB bloons, while your Riccochets and Bombs can clean up the mess.

Not attacking anyone for 72 consecutive hours gets you into Pacifist Mode, as I am in now ;)
