I'm sorry, but why was it more exciting to know the character ahead of time?
I don't really know the "why" of it. In thinking about it, I wonder if I would have felt this way if the podcasts were posted on the day the characters were announced (like the first episode).
In thinking more, the official celebration gave us a lot more than the podcast (though the podcast was one of the best things out of the celebration). Official social media sites have had several posts about the weekly character (I haven't noticed that with ToughPigs), occasional merchandise, the magnets (though you'd have to go to the theme parks to get them), occasional social media posts of the Muppets talking about the weeks character, occasional Q&A posts on social media (though it seems it was limited to the main characters), fans sending in fan art and photo dumps of the fan art on the social media sites (I have seen some fans post fan art, haven't paid a lot of attention to it).
With this second season, the character focus feels a little more like a "one and done deal" each week. Sure, fans comment about the episodes on social media and we talk about it on the ToughPigs discord, but now it's just a podcast. A very good podcast, just like many of the other ToughPigs podcasts, of course.
We do get at least one thing this season that we didn't get with the initial 70 Years 70 Muppets. With no apparent restrictions from Disney this time around, the TP discord has posted hints on the next character the day before, though I sometimes forget to check the threads until after the next episode is out (which I did with Nigel).
