Hush Slush

Hush Slush is an elixir mentioned in the Barnes and Noble Nightfall Special edition section in Keefe's perspective. It's effects wipe out the victims voice for eight hours, as shown by Keefe reflecting on the glorious eight hour without Ro's voice. In reaction to this, the princess located all of Keefe's statues of pranking supplies, and possibly slipped a gurgle gut in his breakfast for payback. This elixir works both on elves and Ogres, and is presumably sold at Slurps and Burps.
