Stacy Campbell

Stacey Campbell was on the Adipose Industries diet and took one tablet per day for three weeks. Donna Noble visited her pretending to be from Adipose Industries. Stacey was preparing to dump her boyfriend. Donna started playing with an Adipose pill necklace which triggered the Adipose reaction in Stacey. Stacey saw an Adipose and so Matron Cofelia activated full parthenogenesis. Stacey's body swelled then collapsed into a pile of clothes and Adipose emerged from the remnants. (DW: Partners in Crime)
