Gru'um Ropple
one of Jabba the Hutt's associates, Gru'um plotted to assassinate Jabba sometime prior to the Battle of Yavin. A blue-skinned, hairless humanoid, he planned to use the humanoid droid Miramba to carry frekkers into the Hutt's palace. His plot coincided with Bib Fortuna's first attempt to kill Jabba. Bib tried to remove Gru'um by planting a blaster in his robes. Jabba had Gru'um and Miramba imprisoned, but the frekkers were unleashed anyway. In the ensuing confusion, Jabba was actually rescued by Bib Fortuna, who tried to keep the Hutt alive for his own schemes. Gru'um's fate was sealed when Jabba discovered where the frekkers had come from.
