Squid Island crisis

The Squid Island crisis was a crisis in Squid Island initiated by a butterfly effect stemming from an intentional misinterpretation of Jelly’s words by Slogo resulting in mild damage to parts of Jellyland and mild vandalism from Crainer, later snowballing into a massive forest fire on jellyland after jelly tried to blow up Slogo. This plunged Jelly into a negative mindset, and thus when Crainer accidentally murdered King Glowey II, Jelly and Slogo decided to blow up the lobby of the Crainer's Skyscraper as retaliation for the killing of King Glowey II and other issues. 
This resulted in a negative mindset burdened upon Crainer, Jelly, and Slogo, resulting in further escalation and tensions. Over the course of the crisis, Jelly repeatedly escalated tensions by trying to rig TNT and redstone across the island and more specifically in Crainer Land. 
The ultimate culmination happened when Jelly killed Floppy and renamed him, and disguised him in the Bork Co. fish product to be eaten by Crainer, resembling a previous troll by josh in Bee Town. This, along with Jelly framing Josh as his accomplice, lead Crainer to start Squid War II. More information there.
