The Rhino policy for Easter Egg collection is to keep cheery. That is the Rhino system, and is consistently effective. Humming and skipping enhance the quest, and those techniques seem to lure the Eggs themselves; they place themselves right in the path of the wily hunter.

Then the Cunning Collector swoops down on the prey, and fills the E. Basket in jig time.

All adds up to a satisfying safari. That said, one must be vigilant. Bear in mind, you are not scavenging alone.
