Gertie was the elderly charwoman of the prison which Mr. Toad got sent to after being framed for stealing the motor car whom the other unruly prisoners constantly made fun of because of her numerous signs of aging. Upon seeing how sad Toad was in prison, Gertie was to have felt sorry for him and attempt to cheer him up by singing a deleted song entitled Be a Stout Fellow. Eventually, Toad would've been able to pursuade her to lend him her uniform so that he could disguise himself as her and escape jail undetected.
Trivia[]
Her name may be a reference to Gertie the Dinosaur, an old cartoon character. Likewise to dinosaurs, this particular Gertie is also old, giving this theory more credit.
