This article contains plot details about an IMPORTANT EVENT!!!!
After clearing Mt. Steel and at least 5 rescue missions, Caterpie will come up to the player and request help for his friend Metapod, who had become lost in Sinister Woods. Team Meanies then overhears this and offer to rescue Metapod themselves, asking to be paid handsomely as a result. Due to Caterpie's hesitation, Team Meanies then challenges the main player and their partner to a race to see who gets to Metapod first.
The player then traverses the floors of Sinister Woods until they happen upon the final 13th floor, where Metapod is supposedly in. Just before you get to Metapod, Team Meanies shove ahead and a battle ensues. After defeating Team Meanies, Metapod then asks if the player had come to rescue them, and upon realising that they were asks to be escorted back to the front of the Team Base. Caterpie then thanks the player and their partner, but constantly reminisces over not having any money, to which the partner reassures him that they do not need money as a reward for the mission.
