Who is the fourth unicorn?

The power struggle that raged during the redesign is over. Christina, Jake, and I retained our rank as Unicorns of the Hydrocalypse. Michael, however, who has returned to his native Dutch land was demoted from Unicorn to Horse. He remains an important part of the Hydrocalypse Industries family in his reduced role, but there must always be four Unicorns. In recent days someone has risen to fill Michael's place. The identity of the fourth Unicorn will not be revealed today, but we are ready to release footage of this person in action.
