There is a good glitch in the zelda classic RC candidate 2.5.1

I gave it a gold star because I like the glitch. In the 1st and 2nd quests when killing the Digdogger after blowing the whistle and it splits into 3 mini Digdoggers if you kill one of the mini Diggdoggers and leave the room then come back in the room where the Diggerdogger was it is gone for good.
