The boost works for the Big Chinchompa Distraction and Diversion also, so a good tactic is to have the protea flower equipped until you want to dump your moths, at which point you should equip the enhanced yaktwee stick. This boost will stack with bonus experience. Upgrading the yaktwee stick is a requirement for the completionist cape. The enhanced yaktwee stick is lost upon death. Return to Yaktwee and buy a regular yaktwee stick and then talk to him about upgrading to recover the enhanced yaktwee stick.
