Whenever Digit malfunctioned, Muppet Central's maintenance man, or rather, maintenance bird, Lindbergh would come to repair him....usually using a sledgehammer when nothing else would work. His function was very similar to Beauregard's, the difference being that Lindbergh was actually competent at his job. Lindbergh has a very positive personality and doesn't consider any job he's tasked with too big for him. It's actually a shame he didn't appear after The Jim Henson Hour.
