In the past I've mentioned Pokemon I thought should get metronome and interestingly a far few did this generation (and honestly most make sense) But the one that got the move that I noticed was Galarian Meowth does but only Galarian Meowth and none of the other meowths (despite there also being a TR in gen 8 where Galarian Meowth got came from and did not get the move then). This is probably to do with Persian being quadrupedal (given its Japanese name wage finger). But if that is the case I'm not sure why the move was also added to the limbless Shuppet this gen rather than just to its evolved form.
