Synopsis
Kari is starting to have freaky nightmares now. T.K. notices her disappearing in class once and she looked like static! She disappears into a world where there were these Scubamon with dark spirals who pleaded for help. Kari calls out to T.K. and Gatomon. T.K., Patamon, and Gatomon see her in the sky and go through a gate to fight Airdramon. Pegasusmon destroys the Dark Tower, allowing Gatomon to digivolve to Angewomon. She defeats Airdramon but for some reason the Scubamon turn all shadowy and they try to take Kari to be their Queen so they can defeat their undersea master. They leave warning them that their undersea master will come after them.

Quotes
"Ah, what the heck. I got nine lives."
 * —Gatomon making a snap decision to follow T.K. and Patamon through the portal to the world of darkness.

Animation errors

 * Gatomon's tail ring can be seen during digivolution, even though she lost it. This is a result of using the same digivolution sequence from the first series.

Dubbing changes

 * T.K.'s response to Kari during the school break is different in each version. In the English dub, T.K. tells Kari that he cares too much to let her be taken away, whilst in the original episode, T.K. is angry at Kari for relying too much on her brother Tai.
 * In the original, the "Scubamon" wanted to mate with Kari in order to create powerful progeny in order to combat the new god. This is glossed over in the dub, where they instead want her as their Queen.

Digimon references

 * Later on, in the episode Genesis of Evil, it's revealed that Ken Ichijouji also traveled to the Dark Ocean, before he became the Digimon Emperor.

Real-world references

 * In the opening title, a column of DigiCode appears displaying the following:


 * This translates to "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn" (フングルイ ムグルウナフ クトゥルウ ルルイエ ウガフナグル フタグン), an occult phrase from H. P. Lovecraft's The Call of Cthulhu which means "In his house at R'lyeh, dead Cthulhu waits dreaming". Later, when Hikari is alone, she walks past a sign that reads "Innsmouth" (インスマウス), a fictional town in Cthulhu Mythos.

Miscellaneous trivia

 * This is the first episode in the series to feature a digivolution to the Ultimate level. There won't be another normal digivolution of this kind until the episode Destiny in Doubt.
 * Kari announces the episode title in the Japanese episode.
