I don't know what it is but they should add a premium upgrade called "Weird It Up!". It costs 470 Ninja Kiwi Coins. It allows all towers to be upgraded fully on both paths. However this will take away 5 Ranks and lead to some odd but awesome BTD 5 props to use this wisely (don't use it on Sun God/Robo Monkey or something like that or thats to overpowered.)

A better idea to use Weird It Up! is to use it on a Dart Monkey - you get a Super Monkey throwing Juggernaut balls rapidly!!!!!!
