Love it but I'm stuck? – LEGO Harry Potter: Years 1-4 Review

I love this game!!! But right now I have to make a potion to regrow Harry's arm I think I have to kill a thing ( It looks like a toad pickle ) and IT WON'T DIE!!!!!!!!!!!!!!!!!!!!!? I know it's just a game but it's frustrating!!! I recommend it to all of the Harry Potter fans out there.
