doofensmirtz had built in an inator that would turn roger into an almost exact copy of his daughter but something went wrong an instead it turned ferb into an almost exact copy of candace with the ability to turn others through touch. phineas was later turned but due to having been warned by candice(isabella) he was able to build a device on his arm that let him keep his memories and personality. buford was also turned and became baljeets big sister #candaceinfestation#phineasandferb#story
