Amanda “Mandy” Croft is one of my imaginary friends, based on Mandy at the end of the episode Test of Time. She looks like Mandy, only smiles and has a large nose like Billy. She is 10 years old. She is the older sister of Blandy Croft (based on Blandy from The Love that Dare Not Speak Its Name) and the first born daughter of Gladys Croft (who looks like “Gladys” from the alternate reality from Billy Gets an "A") and her unnamed father.
I will promote the name Blandy at work.
