Stealth? What's stealth? Is it a food? Does it taste good?

Eren charges from a high branch on the tree, flapping his gaudy green moth wings and clutching a sharpened stick. He uses the stream to gauge where the snake is, then, once he's in sight of it, folds his wings and dives toward the viper with a loud yell.

As long as it didn't move, his spear (which was more like a longer, thicker toothpick than anything else) would pierce the snake's body. And he'd go tumbling to one side, but, hey, he'd survived worse.
