Time Bokan

Dr. Kieta, the inventor of a time-travel machine, is lost on a test run of his machine to the prehistoric past. When the time-space craft returns to the present, his young assistants are surprised to find only a parrot in the cockpit. In their hurry to find the missing scientist before it is too late, the youngsters set out on a time-space hunt without any clear destination.
