From Tardis Wiki, the free Doctor Who reference
A version of Sarah Jane Smith existed in the Daft Dimension. She was a companion of the Fourth Doctor.
The two of them visited a planet inhabited entirely by life-sized Jelly Baby people. (COMIC: The Daft Dimension 502)
By one account, she and the Doctor travelled with a robot cat called Kit-10, who caused a lot of problems for the pair. (COMIC: The Daft Dimension 588)
