An Audible Original audio drama set in a summer camp during the year 2005 in which a camper Micheala "Mookie" Hooper is sent to a summer camp in order to help her recover from a severe trauma (though it would be a spoiler to say what!). Aside from interacting with quirky characters seasons of this show see dealing with a girl who mysteriously disappeared, and a camp director played by Daniel Radcliff who claims he is the grandson of the camp's founders. Unfortunately I forget the exact details regarding what the third season is about but I know it involves Mookie finally confronting the trauma behind why her mom sent her to camp in the first place.
The show is differently not for younger kids -to my memory it contains some illusions to nudity. But it is incredibly well performed and orchestrated. Other talent in the show includes Jamie Lee Curtis who not only created the show but also plays the camp director and Weird Al who plays Fred Schifkowitz - though I forget who he is in the show.
There's probably a lot of other great kids content on Audible that could make for amazing Yoto Cards even if they were just digital which is why a partnership between the two in some way (even if it just meant you could link your Audible and Yoto accounts together and access originals from the Yoto App!) would be honestly amazing.
