Krontonian
From Tardis Wiki, the free Doctor Who reference
The Krontonians were a species encountered by the Doctor.
In one of his letters for Doctor Who Weekly, the Fourth Doctor recalled the time he had helped find out that a Krontonian ambassador's missing seal of authority had been swallowed by his 78 year old son.
