He is the page of Sir Tuxford in King Gregor's court. Cavin befriended the gummis in the first episode and shares the same ambition as Cubbi's-to become a knight. Cavin also had a Gummi Medalion, given to him by his grandfather Sir Gawain, that opened the Great Book of Gummi, the source of all Gummi wisdom. The young squire also had a crush on Princess Calla, which was requited. Cavin was voiced by Christian Jacobs in season 1, Brett Johnson in season 2, David Faustino in season 3, Jason Marsden in seasons 4-5, and R.J. Williams in season 6.
