Terry the Tortoise as himself
Terry the Tortoise is Jennifer’s loyal pet companion, and accompanies her through the ages. Despite what may be assumed he is not the namesake of the eponymous showrunner Terry Matalas. Terry the Tortoise is in fact a genuine Terry, and given how old Tortoise’s can live – may even have been a Terry before Terry Matalas was.
Terry joined the cast in Season 2 episode Bodies of Water.
