If one clicks on the fish in the moon during the stampede scene, the original comic starring Doki and Nabi (titled "Only You") followed by thanks from the creator will appear. This is only in the English version of the short; the Korean version displays what appears to be a snapshot of an animation panel in Flash, presumably from step two. The flying fish on the moon is a reference to another SamBakZa animation, "Hot Fish", in which Doki and Nabi make an appearance. This is currently officially unavailable due to copyright issues with the soundtrack, "Sera" by Jeo Qu-cheon. However, it is available on YouTube. The signs on the walls of the subway station read "Bulldog Mansion". Clicking on them will give a link to their (now defunct) site. Step three begins an in-depth trilogy of sequels to the first two videos. It premiered at SICAF (Seoul International Cartoon & Animation Festival) on May 21–25, 2008, and was posted online on May 30. Its soundtrack is the Korean pop song "3차성징" ("Sam-cha Seong-jing", translating to "tertiary sex characteristic") by T.A.COPY. This step portrays Doki and Nabi's first date. Nabi begins as an unwilling recipient of Doki's love, but starts to reciprocate as the date goes on. The Jjintta Set and their objections are upset when Doki tackle-hugs Il-ho, then turning the hug into something akin to a nelson. In the end, Nabi asks Doki out on a second date, and their relationship blossoms into a mutual romance, and they share their first kiss. The intermarriage theme is more prominent in this episode, as are the consequences of their relationship: the step ends with a rock thrown through Nabi's window. Clicking the cloud on the top right of the loading screen triggers an alternate opening that focuses on Doki making her way to Nabi's house. Clicking the black poster during the scene with the neighbors opens T.A.COPY's site in another window. The scene where Doki befriends the hedgehog is a nod to Hayao Miyazaki's "Nausicaä of the Valley of the Wind", in which Nausicaä tames Teto the fox-squirrel. During the scene where Doki is chasing Nabi, after all attempts to capture Nabi fail, Doki throws a Poké Ball at Nabi's head.
