Bim bam bum - S2.E2

Bim and Bum are two friends with an extraordinary job: to make holes, ready for use anytime somebody needs a hole. Sievemakers, buttonmakers and cheesemakers all need holes to do an excellent product. Bim and Bum can even make a hole for a railroad tunnel. But professor Balthazar must rescue them when they and their work shop fall into a hole in the ground.
