Ferris Gear (フェリスギア Ferisu Gia) is a Keychain for Sora's Keyblade that appears in Kingdom Hearts 3D: Dream Drop Distance. It is obtained after clearing Prankster's Paradise.
The Keyblade's name and overall design are derived from "Ferris wheel", a popular amusement park attraction. The teeth resemble a large ferris wheel, connected to the blade, a red and white striped pole, by a gear. The hilt is a gear shaped clock, and the guard features clockwork machinery. The Keychain is another clock, the chain itself being red, with white arrows pointing out from the "loops" of the chain.
