Anyway,

Sorbet is the younger twin, while Sherbet is the older twin. The former is fun-loving, carefree, rebellious and extroverted. The latter is same except she is introverted.

Their birthdays are 20 January.

They are a pair of young women who are huge fans of Hank. Initially they were hired by the Sheriff to track down and kill him, but instead fell head over heels over him. These sisters tend to fight over Hank to win his affection, but he himself thinks they get on his nerves.

The GT originated from Uganda, and at first came to Nevada, USA to look after jobs until they were recruited by the Sheriff into the A.A.H.W. As soon as Sheriff found out the twins turned back against him and were crushing on Hank, he fired them, but they didn't care.
