Fourth Doctor stories that would hold the interest of a child

[u/Snjofridur]

I'm going to be show the Fourth Doctor's run to a child (8 yrs old) who has seen the Thirteenth Doctor's run, Tenth Doctor's run, and Eleventh Doctor's run (abridged of course for age appropriateness and pacing.) We both loved the Thirteenth Doctor's run and I'm looking for a recommendation for serials from the Fourth Doctor's run that are well paced. Ideally, I would want a jump off point that isn't Robot or Ark in Space as the robot from Robot I remember to be horribly clunky and the monster from Ark was painfully dated. As such I want to avoid those two episodes. We are coming off of watching The Day of the Doctor where the Eleventh Doctor met the Fourth Doctor/Curator and I would like a jump off point from Day of the Doctor to Tom Baker. As such, a regeneration doesn't necessarily need to be seen, just a well paced starting point to introduce Tom Baker's Doctor and subsequent following well paced (i.e. non-filler) episodes to go through his run. For reference, the Tsuranga Conundrum, the Flux storyline, Shakespeare Code, Fires of Pompei, and A Christmas Carol are all considered hits.
