Name: Roolna (Stage name: Roll)
Species: Armadillium vulgare (Common Pillbug)
Mischievious and inclined to improvisation, Roll sometimes has trouble adhering strictly to his brother's well-planned-out routines, which infuriates the other. Roll's temper, however, is just as quick, and he does not hesitate to argue or fight back if Tuck expresses his disproval.
