The Piximon Cometh

The Piximon Cometh is the eighteenth episode of both Digimon Adventure and the Digimon anime series.

Summary
After more walking through the desert, the group run into Kuwagamon, and gets a hold of Tai. All seems lost when Agumon hesitates to digivolve (after the SkullGreymon incident), until Piximon rescues them. Piximon is known for his tough training of other Digimon, and leads the group to his hidden home where their training begins. While everyone else mops floors, Tai and Agumon are sent into a bizarre world where they must learn to face his fears. When everybody is sleeping, Matt and Izzy's tags begin to glow. They are lead to a well where the Crests of Friendship and Knowledge are found. However, being outside Piximon's home, Etemon detects the two and sends Tyrannomon after them. They escape into Piximon's home, but Tyrannomon breaks open the invisible shield hiding it. With the other Digimon still tired from yesterday's training, their hope rests on Tai and Agumon. Luckily, Tai and Agumon overcome their fears and escape their prison, and Agumon digivolves to destroy Tyrannamon and the Dark Network surrounding him.
