Finders Keepers Cover Story
The Magician's Assistant is the ninth episode of Underground Ernie. It originally aired on CBeebies on June 15th 2006.


The trains are excited as Paris is returning with famous magician Maestro. Jubilee goes to pick up his assistant from the airport, but it turns out she missed her flight. Maestro chooses Millie to be his assistant for the evening performance, which she gladly accepts.

Paris goes to pick up Millie, but recommends that she try on some new clothes to wear in her performance, and Paris is very fussy. Maestro can't rehearse without Millie, and goes on a wild goose chase to find her.

As Maestro leaves to find Millie, she arrives back at the theatre. Ernie offers to rehearse with her, and when they try the disappearing box trick, Ernie fears he's lost her, but Maestro arrives back in time and Millie shows up.

Maestro's performance is a hit, and that night, Ernie decides to show some magic tricks to the trains, much to their delight.
