- Gralexy was first mentioned in The Valley of Peace as "aliens working with the government".
- The Enderman the Doctor uses to teleport back into the Valley can be seen in the same area in Arabah.
- The portalroom under the embassy is based on the portalroom in Gravity Falls, with the same music playing when the portal opens in the show.
- The planet Gralexy is just a slightly edited Mondas from Whoville. The Grals are based of the co owner Gralex.
