Favorite Episode
I'd have to find a copy and watch them all again but I suspect my favorite episode is Three Wishes. You get to see some zaniness with the wishes and of course Mullins becoming a tougher pirate than Hook by just being 'half the pirate he thinks he is' is a bit of a treat. Not to mention Hook being done in by the croc and then saved by Peter's wish.
I'm also partial to the first episode of the series with the Ice King, if nothing more than to see the evil twin scenario with Pan. The problem with that episode to me seems to be that it ends all too quickly, so much more mayhem could have happened and more tragedy because of Pan's selfish thirst for fun but... we only get a taste.
