Ultra Death

"Died by drinking orange juice then toothpaste" This ending requires you to buy the orange juice at the 24-Hour Convenience Store, which costs $30 in Cash. Once the orange juice is acquired, go back into your house and enter the bathroom. Drink the orange juice and then pick up the toothpaste and drink it. This will cause you to explode and be teleported to the "Void", where you will meet Dummy. They go on to explain that you have to get all of the endings, and that if you get stuck, just come back by drinking orange juice and then toothpaste so that they can give you hints. Once they are done talking, you will have gotten this ending.
