The Legend of Zelda - 06 - That Sinking Feeling

In an attempt to romance Zelda, Link leads her to a secluded forest glade with a stream running nearby and a sculpture. Before the encounter advances too far, an entrance to the Underworld appears and Ganon's Tektites ambush the couple. They defeat the monsters, and undeterred, Link attempts to resume their encounter when the sculpture nearby is inexplicably pulled straight into the ground leaving no hole and no trace. Zelda grows impatient with interruptions and decides to assault Ganon in the Underworld, only to watch as the entire Hyrule Castle is also pulled underground just as they ride off.
