Idk if you know but there’s a fan story by the brendam engine called bill and bens excellent adventure that ends with them meeting Alfred and Judy
YESSS I've seen that! :D I've seen the entire four-episode little series they did and I quite thoroughly enjoyed the whole thing. As someone who can be a bit hit or miss with stories about the twins sometimes, and maybe a little starved for content (LOL), I very much enjoyed watching through it!
I remember as soon as Cornwall was mentioned in that episode I had a sneaking suspicion I knew where it was going, but it was a wonderful surprise nonetheless! ^^ It was a delight to see all four of them together hehe I won't spoil anything further from it in case any of y'all haven't seen the series before, but I highly recommend checking it out!
Here's a link to the first episode! The rest can be found on a playlist on their channel for their "Endless Railway Series", but in order there's "William and Benjamin", "The Two-Faced Race", "Heroes of The Quarry" and, ofc "Bill and Ben's Excellent Adventure" ^^
There's a little arc throughout the series too and it's a lot of fun. ^^ So enjoy fellow bee content enjoyers! And thank you for reminding me of it, I might just have to go back and re-watch it all again now LMAO Thank you for the ask!! ^^
