Derpy and Dinky are sisters like no others. But even though Derpy tries her best to take care of Dinky, a few things had come up recently about Derpy's clumsiness, and forgetfulness. Now, after Derpy was considered "A danger to herself and others, including Dinky", Derpy has to prove that Dinky is safe with her. Will she lose the only family she has, or will she save her little sister from becoming an orphan?
