The Baby Dragon is a mob that was added in the "Animals Master" update and is one of the few neutral mobs in the game, the others being crab, baby lava dragon, boar, and king crab. If you hit a baby dragon with a saddle, you have a 1% chance of taming it, which can be increased by wearing the Crown of Luck to 5%.
Despite being neutral, this mob can break structures.
Baby dragons are slightly faster than arctic foxes, and thus you need to attack them slower. Killing it around a fire is possible if you lead it out of the cave, although this difficult to do without taking damage. Note that they deal less damage than arctic foxes.
