Prince Louis is reporting for duty.

The 5-year-old participated in his first official royal engagement on May 8, joining his parents Prince William and Kate Middleton and siblings Prince George, 9, and Princess Charlotte, 8, for The Big Help Out.

For the event—which was part of King Charles III's coronation festivities and encouraged people to volunteer in their local areas—the Prince and Princess of Wales and their children worked with the Scouts to help renovate their meeting place in Upton, Slough.

Louis and George took turns sitting with their dad in the excavator to dig into the dirt. While George also used a drill to assist with some woodwork, his little brother teamed up with Charlotte and Kate to help with the shoveling and wheelbarrowing. In addition, the kids did some painting, wood staining and even left their handprints on a mural.

But it wasn't all work for the young royals. George, Charlotte and Louis also tried some fun activities, including archery and roasting marshmallows for s'mores.
