Milly is very excited about going to school because it’s Superhero Day. She has fashioned a costume out of tin foil and a tea towel but she’s a little bit sad that she doesn’t  have any REAL super powers. Or does she?

In the classroom Super Milly spots that William is sad because his dad forgot it was a dress up day. She hands him her superhero badge and tells him he can be Wonder William. She cheers up Fantastic Flora with some jokes. She settles a dispute between Amazing Archie and Spider Sid and she comes to Incredible Iqbal’s aid when his pet spider escapes during Show and Tell.
