Ocarina of Time

The Ocarina of Time is the artifact from the Zelda game of the same name. As of the end of Wibbly Wobbly, Timey Wimey, it is currently in the posession of Trope-tan, for reasons which will probably be explored in What Could Have Been.

Trope-Tan uses it to play the MST3K theme tune, though the Ocarina refers to it as "The Anthem of Mighty Satellites". This song has the ability to close plot holes, or at the very least to stabilise them.
