AlterniaBound?

Alterniabound, titled in Застрявшие дома as [S] Past Karkat: Wake up, is an interactive Flash segment in Act 5 Act 2 starring the trolls in their Ectobiology Lab in the Veil, soon after their first contact with the kids. Its name is based on the video game EarthBound.
The Flash allows the player to Поиск through the lab, examining objects of interest and collecting items from treasure chests (although none of the objects do anything apart from getting a humorous reaction/description from the character).
