When the pelicans are friends with a family of fish. So when a family of fish has baby fish and when those baby fish grow up and are ready to move out of home the pelicans scope them up in their chin
beak and fly away to a different
beach and deposit them at that beach. Then, when those fish grow up and have baby fish of their own and then those baby fish grow up and are ready to move out the same
pelican friend scoops them up in their
beak chin and fly's back to the original beach. Then deposits those fish with the grandparent fish. Thus creating the Pelefish cycle!
