My sudden appear is shocking - He don't show his face until he catch you, and he's a big snake, beat that Anaconda.
when I get weak you have to hurry - When he's weak, you'll have to hurry.
Otherwise you'll feel my fury - Otherwise, he cast Beta, strong magic at that time.
And your vitality is fading - You'll probably lose.
