Shelly

Shelly is a mining turtle 'befriended' by Glitcher and Buncible in Crimesend Life Klink. Shelly helps the duo to escape the prison, and was last seen constructing a tower of infinite height in the desert.

Origin
Of the many turtles that service Crimesend, Shelly was the one that delivered food to the cell of Giltcher and Buncible on the day of their escape. In their eagerness to get the food, Shelly was picked up and ate the food herself. Buncible was then able to open the inner doors of their cell by giving Shelly the instructions "oi u shelly beast y dun u spring us outta here roight like", and Glitcher programmed her to destroy the outter cell doors.

Between episodes 6 and 7 of Tekkit Toolbox, Glitcher and Buncible spend four hours watching Shelly dance, then take her with them, which is when they give her the name Shelly.

Horrible Freedom
Shelly travels with Glitcher throughout the rest of his time in Crimesend, appearing again amongst the wreckage of the crashed escape vessel. At first Glitcher and Buncible think she is dancing for joy at their survival, but looking at her command prompt see that she was dancing at their apparent demise and is dismayed to see that they live.

Glitcher programs Shelly to build a house in the desert using the iron from the wreckage, but neglects to leave a hole for the door. Buncible, meanwhile, longs for a larger building and tells Shelly to build the house 6603 metres tall, which she continues to do until she runs out of building material far beyond their reach.

With no home and no materials, Glitcher and Buncible are forced to leave her behind and trek through the desert.
