I just saw that episode the other day and it was a missed opportunity for a tickling scene given the set up, though with Argit going around barefoot and having a tendency to end up in all kinds of trouble there could be plenty of opportunities for tickle situations involving him. Since he's an unscrupulous manipulative little weasel/rat/porcupine he definitely deserves some tickling so it's good to see another one of your what-if situations rendered so perfectly.
I prefer to think of them as an un cut versions. They did happen but they were edited out for being too cruel ^^
In each case I try not to ruin the flow of the story or the character when I introduce a scene like this (cant say the same for my older stuff) so that its feels believable rather then like some out of place random fan fiction.
