Shovels are tools required for shifting those shovels, digging to the sound, invented by none other than the Dig-Its. They are also used as utensils on the set of Twiba's Cooing Sgow. Other tools can be used for this ability, but mainly shovels considering how the Dig-Its make up the most of those who can dig it, and use shovels. To them, using shovels for this ability is ground-breaking (pun intended). Although the Dig-Its do not really need shovels for their excavational needs, as they can use their apples, or their slimy bodies.
Shovels were invented by a Dig-It who lived in a Long Time Ago in a Galaxy Far Far Away, known as Twtis Shovel, a Dig-It who was determined to find an easier method of digging it than using his dirty, slimy wormy body. Shovels became very popular in the Dig-It industry very quickly, as they were also used as weapons to fight off anyone hated by the Dig-Its (pretty much @everyone), before their overabundance of weapons increased more than tenfold.
