I have Sonic and The Black Knight for the wii. but i don't know how to defeat king arthur. How and when do i attack him? plz help

First of all, I'll let toi know, after toi beat him, it isn't the end of the game. ;) It's been a while since I've played it, but toi run up to him, avoiding all attacks, and then balançoire, swing the Wii remote when it tells toi to. Hope it helps.

What I did was I used soul serge over and over. It worked
