1) Bloon Liquefier (4/2 and not). Bloon Dissolver already pops ceramics. Short tracks? A bit of support and you're done. Four Bloon Liquefiers don't even beat round 43 on Down the Drain. 2) Summon Whirlwind. The whirlwinds are too weak and last too few. 3) Long Life Bananas. No explanation(s) needed.

No DC requires any of these upgrades either.

Other useless upgrades include: 4) Tempest Tornado. Screws up your defense when there are regrows. Even if you use this to blow bloons up, you still have Bloonjitsu, which is a much faster tower, much better MOAB popper, less expensive, and it's able pop camo with no upgrades, which makes this useless. Also, this turns four regen rainbows into infinite, which is definitely not great to see. The very rare usefulnesses of this upgrade are round 63 and 78 rushes when you barely have any effective tower against rushes. No DCs require this either. 5) Pineapple Present. Not accurate. 6) Operation: Dart Storm. Not accurate, and unlikely to hit MOABs with three or more darts either. 7) Super Range Tacks. Range increase is lower than Extra Range Tacks', and twice as expensive. 8) Blade Shooter (especially if 0/3). This outclasses Tack Sprayer in every manner. It's more expensive, not accurate opposite to what to description says "harder for bloons to avoid", shoots 8 projectiles only which means less damage to MOABs and ceramics, and it's incredibly slow without the other path upgrades. 9) Ray of Doom. Cannot pop a ZOMG even in the longest tracks. 10) Bloon Trap. Three ceramics outclass it. 11) Glue Hose (2/3 and not). Two x/2 glue gunners do its job fine, and with this upgrade, Bloon Dissolver cannot be bought which means no ceramic popping power. 12) Glue Striker. Glue Hose glues every bloon (or almost), so... 13) Viral Frost. Arctic Wind is enough, Viral Frost is easily outclassed. 14) Absolute Zero. Many upgrades outclass it. 15) Monkey Intelligence Bureau. No need to explain. 16) Monkey Town. Weaker way for earning money. 17) Monkey Bank. Not any better than two Banana Plantations. 18) Banana Investments Advisory. By the time you can get this, you can get 4/x too. 19) Flash Bomb. Easily replaceable by Bloon Impact. 20) Glaive Lord. It takes 10 of them to destory a MOAB on Death Valley. Even a MOAB Mauler 0/3 does more damage.
