This mod adds 4 types of Dragons which will spawn rarely across your Minecraft worlds. I plan to add more in the future. The current 4 Dragons are:

Horned Dragons:
Spawns on the surface of any Overworld biome. Shoots explosive fireballs.

Horned Dragon

Cave Dragons:
Spawns underground in any Overworld biome. Shoots explosive fireballs.

Cave Dragon

Ice Dragons:
Spawns on the surface of any snow-covered biome. Shoots Iceballs which freeze anything they hit.

Ice Dragon

Swamp Dragons:
Spawns on the surface in Swamps and Mangrove Swamps. Shoots Poisonballs which create an AOE inflicting Poison.

Swamp Dragon

All Dragon types are tamed with Dragon Feed, crafted from 5 Chorus Fruit and 4 Diamonds, resulting in 8 Dragon Feed.

Dragon Feed Recipe

The Dragons can also be bred, which you can then feed a baby Dragon Golden Dragon Feed, which will keep it as a baby forever.

Golden Dragon Feed Recipe

When riding a tamed Dragon, by pressing [ R ] you can shoot fireballs.
Pressing [ TAB ] will switch between Ground travel and Air travel.
Pressing [ SPACE ] makes the Dragon jump.
