However, he passed away before his quest was complete, and would not be allowed to rest until his spirit could aid a living Gummi knight to continue the quest.
One day Cubbi comes across his tombstone. As Cubbi had previously been commissioned an official Gummi knight in "The Knights of Gummadoon", Sir Gallent's spirit is released, with only Cubbi bring able to see the ghost.
Cubbi is aided by an amulet, given to Gallent by the Great Gummies, which serves as a compass that glows brighter the closer they get to the Doomsday Clock.
Along their journey, Cubbi is also taught important lessons of knighthood by Sir Gallent, such as not using Gummiberry Juice until the point of true need, or that being a knight is not just thrillseeking.
Cubbi helps Sir Gallent in his quest, and Sir Gallent's ghost is finally able to rest, leaving Cubbi with the amulet compass as proof that their quest really happened.
