How to Train Your Dragon 2 featured a serious upgrade in the weapon department. When Hiccup (voiced by Jay Baruchel), finds himself in a cave full of the titular beasts, he pulls out a hot new blade.

In this Blu-ray/DVD extra, exclusively premiering on Yahoo Movies, Hiccup walks us through the special features of his flaming homemade dragon-deflecting sword. And while there’s some “sticky napalm-like fire” in there that could do some real damage, take heart — he only uses it to scare the fire-breathing creatures.

How to Train Your Dragon 2, which grossed more than $500 million worldwide, is now on digital HD and will be available next Tuesday on Blu-ray and DVD.
