Okay Gulliver - let's go out with a bang! Finish up with a combo of Reversal, Crunch and Shadow ball - so hit it with Reversal first, and whilst still in contact use Crunch, and whilst you're still holding on to him hit him with the close range Shadow Ball. You did well little buddy!

(If Odour Sleuth isn't still in effect, switch the Reversal to Aerial Ace)
