Sam Wu Is NOT Afraid of Ghosts!. See, totally NOT scared

I'm Samu Wu and I'm absolutely, positively, definitely NOT afraid of ghosts. But when Ralph Philip Zinkerman the Third started calling me Scaredy-Cat Sam after the event that must never be spoken of ever again (so don't ask !) I knew I needed a plan of action : I) Obtain terrifying and deadly pet as sidekick ; 2) Defeat the Ghost King once and for all. Easy ! Right... ?
