Petpet Battle is an extremely lame game that is boring and unfun to play. Because of this, it's a really easy trophy for your userlookup... if you can stand playing it.
Me I cannot. But I could stand writing an autoplayer for it.
This won't win 100% of the time because the game relies on RNG a lot. But by switching between shielding and using head shots, you should get a reasonable win rate. I've gotten the gold trophy using this script before, so I can confirm that this script is good enough for that.
