Grandpa is very excited when his all-time favourite song and dance man Charlie Cheekster makes a return visit to Sunnysands, but the entertainer just feels old and past it - not very cheery at all. Auntie Jules, Uncle CJ, Jason and Jemima try to cheer him up by singing tunes that made him famous, and Elsie and Josh perform a puppet - but when their efforts fail, Grandpa takes on the challenge by shrinking and dressing up as a Charlie Cheekster doll, which leaves his hero enchanted.
