For the people that keep dying when electrocuting yellow:
Make sure you are not electrocuting the cardboard cutout. There is a chance that yellow will put a fake cutout of himself on the door. If that cutout is there, yellow might appear in the door soon. If you electrocute him and still die, it’s most likely that your batter is low. The shock drains a lot of batter so make sure the batter machine is pretty full.
Hope this helps!
