I found a bug when you are trying to get to heatran and are blocked by the camerupt when you select the machete you don`t get sent back but instead set to heatran meaning you can select machete, surfboard or climbing gear and still get past the camerupt and go to heatran.
Also another mistake while fighting heatran.
Groudon opens her mouth wide and fires back with ehr (this is the mistake) own burst of molten rock, . . .
