Pon and Con will be the first Bosses you face in the third world of Jambastion during Story Mode. They like to sprint across the three different levels of platforms, all while a raccoon drops bombs from way above. If you destroy the bombs before they explode, this will actually stun all the Enemies found on the screen. The ESP Copy Ability also does great in this battle, as you can head to a level of platforms where Pon and Con won't reach you before using the ESP energy to hit them hard.
