Watch someone ride a Guardian through the air in The Legend of Zelda: Breath of the Wild
A Zelda: Breath of the Wild player managed to get a Guardian to fly using a Korok leaf and a raft.
The Legend of Zelda: Breath of the Wild's engine allows for all manner of bizarre and creative solutions to problems.
Because the game doesn't spell out these solutions most of the time, players are having fun just discovering how the many tools it offers can work together. Some of these discoveries were perhaps not considered by the developers.
Nevertheless, it's very fun to watch players turn standard tools into powerful, multi-purpose items. In the video above from YouTube channel nesis (via Nintendo Life), the player manages to get a Guardian to fly using a raft and a Korok leaf.
It doesn't go as smoothly in the beginning, given how massive these Guardians are, but he successfully pulls it off... up to a point.
