Since Tai is the only one with a crest so far, he gives Agumon a lot
of food. That way Agumon will be able to digivolve to his Ultimate
form if the need arises.
Joe's tag leads the group to a Coliseum where they hope to find his
crest, but Etemon sends an evil Greymon to attack them. For awhile
it's Greymon versus Greymon. But then Tai gets the bright idea to
put himself in danger, ON PURPOSE, to get Greymon to evolve. Not a
wise thing to do -- Agumon
digivolves to a new form, SkullGreymon -- a really
SkullGreymon defeats evil Greymon, then turns on his friends before he
runs out of energy and digivolves back to Koromon. Thank goodness!
After all the excitement Joe finally finds the crest of reliability.
