"Home Away From Home"

Tai and Korromon find themselves in the middle of a park in Tokyo...Odaiba, no less.  Astonished, Tai makes it away with only a little bit of a hassle, and proceeds to his house.  When he gets there, he finds Kari, his little sister, who is sick.  For some odd reason, she knows about Korromon and Digiworld.  Tai gets a computer message from Izzy telling him not to go back to the Digiworld, but Tai interprets it in the exact opposite way!  He  runs into Ogremon, beats him, and uses the digivice to transpot him and Augumon back to the Digiworld!  But now where to go?
