Ash's Adventures of Wee Sing in the Marvelous Musical Mansion is an upcoming Pokémon crossover made by N/A. It will appear on N/A in the near future.


Ash Ketchum and his friends meet three kids named Alex, Kelly, and Benji and their Auntie Annabella as they go visit their Great Uncle Rubato in his Marvelous Musical Mansion where the music boxes come to life, the hat rack sings and dances, and the door knocker requires you to solve a riddle before you enter. However, in the darkness of the night, several small but important items vanish, requiring the children to locate the thief. Each segment teaches the viewer about musical theory or terminology.
