As a dwarf, Mulch has evolved extraordinary talents, which make him an ideal criminal and later enable him to help the LEP. He is able to tunnel through dirt, digest at an accelerated rate, has luminous and sedative saliva, can sense vibrations through his beard hair using sonar, produces gas containing special chemicals which make him immune to decompression sickness (commonly known as the bends), can absorb liquid through his pores (allowing him to scale walls unaided), and is able to break wind with incredible force and accuracy (enabling him to incapacitate Butler in the first book).
