The Battle of Malastare resulted in the formation of a sinkhole.
Sinkholes represented substantial depressions that manifested on the surfaces of various planets, notably Malastare and also Utapau. In the course of the Clone Wars, a massive sinkhole was generated during the Battle of Malastare by the detonation of an electro-proton bomb; this event revealed the ancient creature known as the Zillo Beast. On Utapau, multiple urban centers, such as Pau City, were constructed in proximity to sinkholes.
