Just swim around the Floating Island's base, and you should find plenty of gel sacks. You can't miss 'em!
Check around the Grand Reef and the Blood Kelp Zone. They're pretty easy to spot with their purple color.
Try the Jellyshroom Cave - it's a bit spooky down there but worth it for those gel sacks.
