The Water Wraith itself has a Property that hides their Treasure from the Treasure Guage, as in OG Pikmin2, Water Wraith chases you through out Submerged castle and because it's always Coded as the same one, if you got Purples in early somehow and defeated the Water Wraith on an early floor, it will drop the Megaphone. This is done so that the Player isn't trying to fight the Water Wraith before hand without Purples trying to get the Treasure and knows to just run as they "got all the Treasure" on a floor. As having the Treasure Gauge going off if the Water Wraith got close would really throw the Player off on each floor...
It is, WW is a very special enemy, even in Base Pikmin2, WW that chases you is the same one as the final floor WW, so if it somehow died early, it's Boss Treasure drops too.
The great sublevel 7 blunder. All of the Canon beetles, who were supposed to be fighting against olimar and his pikmin, realized instead that they themselves were their own enemies somehow, and just instead committed mass suicide
It should be noted that some falling objects only trigger if a pikmin is under them. So when you scout, you should bring a single pikmin and hold A the entire time because then you can actually trigger every trap
i do agree it was probably worth the reset after the crawbster killed all the reds but you actually can kill fiery bulblaxes with purples with the impact damage. You just have to make sure to whistle them before they die from the fire
