Jellyfish will appear from the right of the boat, flying towards the left. Green jellyfish will have a position indicator while off-screen. Touching jellyfish will give rewards.
There are three types of jellyfish:
- Small yellow jellyfish give 10 Glims.
- Large yellow jellyfish give 25 Glims.
- Green jellyfish give Bright Jelly x2.
Before the event starts, you can reposition buildings on the boat up high, to provide ladders to reach jellyfish that appear higher up.
