In Minecraft how do you make a trident?

Trident was added to the Xbox 360 edition with the Aquatic update, which was the last major update the edition received before being completely superseded by Bedrock Edition.

Tridents were never craftable since their release. In vanilla Minecraft, they can only be acquired by killing drowned that are carrying them. The drop rates for the Legacy Console Editions are hard to come by, but there's currently a 15% chance in Bedrock Edition (6.25% in Java Edition) a drowned will spawn with a trident. A drowned carrying a trident has an 8.5% chance to drop it on death. This means that in Bedrock Edition, a trident should drop every 78 (188 in Java Edition) drowned kills on average. These numbers are based on statistics and are not guaranteed. I expect the Legacy Console Edition numbers to be similar.

Since then, the addition of a trident crafting recipe has been a fairly requested feature and plenty of community-made mods and Data Packs have implemented it, but I'm afraid none of these apply to Legacy Console Editions, as modding console games is no easy feat.
