The Eighth Digivice

When one of Myotismon's henchmen is spotted late at night, Izzy is the only one left awake to stop him causing trouble, and ends up tracking a signal from the eighth Digivice.

Synopsis
In his secret location, somewhere in Tokyo, Myotismon is angered to hear that the kids have already defeated two of his henchmen. Meanwhile, Tai is on his way home, and wonders if Kari might be the eighth child. When he arrives home, he shows her his digivice, and is dissapointed to hear that she doesn't have one. But it turns out that the pet cat, Miko, has in fact taken the eighth digivice, and ends up travelling with it in a lorry to another location. Thanks to a message from Gennai on his laptop, Izzy and Tentomon are tracking down another one of Myotismon's henchmen, and find Raremon. As a battle ensues, Izzy gets a signal from the eighth digivice (which Miko has abandoned), and decides to follow it by himself. However, DemiDevimon is also following a signal from his copy of the eighth crest, and finds Izzy. Kabuterimon, fresh from defeating Raremon, comes to the rescue, while the eighth digivice is carried away by a crow.
