Battle of Overseas Pranks

When the Great Egg War ended, a skirmish across the ocean was taking place between the shores of Bird Island and Piggy Island, interrupted when Zeta makes first use of her superweapon on the shores of the latter. The Birds and Pigs were exchanging long-range prank attacks as part of a war between the two that escalated when the Pigs raided the Birds' eggs, leading to an angry counterattack in reprisal.
