I've always heard it as "happy elf".
I am hearing "happy elf" on relistening to it.
I also don't like the way Pickle's exit was written, departing so abruptly without even bothering to say goodbye, and apparently without a kind word to pass along
Made worse by Treguard's own unkindness: deciding that Pickle's an alcoholic based on the sight of one mystery bottle, and making an aside to the watchers about Pickle being demented.
even though he'd developed a decent relationship with Treguard and seemed to be enjoying himself by Series 6.
The last time we saw Pickle, he and Treguard thwarted Lord Fear and saved Knightmare Castle hand in hand (almost literally). Arguably that's more than a decent relationship. It's hard to reconcile that with the mutual bitterness of Pickle's departure.
All in all, I wasn't expecting that post-credits scene, I didn't enjoy it and it cast a shadow over Series 7 for me. (Given that today is exactly three decades later, the phrase "30 years of hurt" comes to mind. This means it's also 30 years since Lissard's introduction and the origin of my username.)
A better farewell for Pickle, and a less antagonistic introduction for Majida, might have helped those of us who struggled to appreciate her character at first. What if Pickle had left a note for Treguard, directly explaining why he had to go and leaving the new Helmet of Justice as a parting gift?
