Squibbler

A squibbler is a fearsome monster with three eyes and two barb- and sucker-encrusted tentacles. The people of Arabesh use ritualized combat against a squibbler to prove a person's guilt or innocence. Cassiopeia encounters one such squibbler when she is put on trial in a plot orchestrated by Ardenzo and his mother.

This squibbler is apparently not a unique creature, as one of the judges of Arabesh suggests they "get another squibbler" for a retrial after Cassiopeia slays the creature with a guard's electrostaff.
