Ages ago, I was training a Togepi to raise its happiness and evolve it into Togetic (and then Togekiss). Had the charm bell or whatever attached, and its only ‘decent’ move was Metronome.
Obviously it exploded and self-destructed way more than should have been likely, but my favourites were the times it pulled out Fling and chucked the fucking one-of-a-kind charm bell at its enemy for 2HP or whatever
