Doug wants to be in the school show, so he asks Waffle to help him with his act. He reveals his new music kit made from household items. Waffle and Doug make music together using all of the different homemade instruments but Mrs Hobbs bangs on the wall from next door. She asks the Brooklyn-Bells to keep the noise down! Doug notices that Mrs Hobbs’ banging is in time with their musical beat - she’s really good. Doug has an idea and invites Mrs Hobbs to come round and join in properly.
