Bulborb Larvae has an intended limit that causes the Empress to fall asleep. May be a smaller limit in Hole of Heroes. Pikmin 2 berries and the bugs don't work. The bugs can't be added, only subtracted from the game. However if you have more than 30 nectars in the area they stop appearing. (Pikmin 3 COULD have this limit) Pikmin 2 berries would not work the same way as this game. Phosbats? Hmm...
