MCPE How to Train Dragon is an unofficial Minecraft Pocket Edition addon developed by Crafting TV. This addon introduces rideable dragons from the popular franchise "How to Train Your Dragon" to Minecraft. Additionally, the addon also includes a script that allows realistic flying behaviors, making the experience more immersive. However, it's important to note that this script is currently exclusive to Windows 10. For other platforms, there is a second behavior pack that enables the old way of flying, which is by jumping and slowly falling.

It's worth mentioning that this is the third beta of the addon, which means there are still features missing, such as natural spawning and actual dragons. Nevertheless, the addon is a great addition for dragon lovers who want to experience the thrill of flying on a dragon in Minecraft. Overall, MCPE How to Train Dragon is a fun and exciting addon that brings a new dimension to Minecraft gameplay.
