This is the Legendary challenge for Week 3 of Fortnite Chapter 2 Season 6, and as usual is split into several levels.
Picking up 10 Bouncy Eggs will guarantee you the Webster's Harvesting Tool. You can then continue your egg hunt to earn even more battle pass XP.
While Bouncy Eggs can be found absolutely everywhere on the map, there are some uncrowded collection "routes" that will allow you to quickly get your hands on a lot of eggs.
Example Bouncy Egg Route
The path shown on the map above is one of the best examples — among others — of an Egg-collection route.
This course has the advantage of being away from the center and doesn't contain busy localities, where other players are likely to collect eggs before you.
Start at the islet northeast of Coral Castle, then loop around the northern wall of Stealthy Stronghold. Bouncy Eggs will be found in large numbers at the feet of trees!
You can eat the eggs directly, or store them for future use. When eaten, they grant the power to make great, weightless leaps, negating fall damage that would normally be taken.
