<human>: Can you summarize the given text in a few sentences?

Today i really, really fucked up. My mates and I saw LA Beasts video where he ate a hole 5lb bag of that deamon-candy, and we figured out the most legendary prank ever pulled. Our school has a large common room. We made sure we were there earlier than anyone else and poured the whole bag into a bowl with a sign that said "Free Candy". Then we sat down and watched. More and more people came pouring in to the common room, and not a single one missed the delicious gummy bears. People munched like it was their last day on earth. After a while, everyone started acting strange. Some rushed to the bathroom and others stayed put but with a noticeable frown on their faces. Then it started. MASS - Panic. We never thought it would get this out of control. You could hear a smattering sound from the bathrooms, I swear I even heard someone crying. The ones queuing for the bathrooms were sweating and most of them ran elsewhere in search of a vacant toilet. A fat kid shat himself on his way out, and after that everyone left the common room, mostly screaming. I am shitting myself (not literally) because if i get busted my whole future is ruined. Oh god reddit, NEVER buy Haribo Sugar free gummy bears, they are spawns of satan.
