|“||Easy to perform, I found this a week or two ago. On the final level put all the fish on the top of the telescope, leave one behind. Once done, use the last one and splash it in the water to the RIGHT of the island for about one minute. Easily done, now watch the island fall apart and float away piece by piece. I'll post pictures later. For more fun, unbalance the island with the last fish balloon and watch the island tilt skyward.||”|

The easter egg involves attaching all Fish but one and waiting. After about thirty seconds, the Fish attached to the telescope will fly away with the telescope, with the pole the telescope was attached to dangling behind. After about 25 seconds later, the entire island will rise up at a tilted angle.
