Perhaps the jellyfish got separated from its group. In the ocean, being alone can be dangerous for a jellyfish as it might not be able to find food easily or defend itself well. So, this separation could be a key event in its bad day story. Another aspect could be that there was a lack of plankton, which is the main food source for jellyfish. So, the jellyfish might have had to swim around for a long time without finding enough to eat, which would make it a really bad day.
