There is a war between two different groups of animals. The Grizzlies send bear cub teams to demolish the Bird Harbour, a base used to train eagles to fight. They succeed in destroying it. The other animal group, the Eagles, seek revenge.
The Eagles, desperate to get revenge, begin working on a project called Expedition Grizzly Hunt, a weapon that is thought as the best way to defeat them in the war. It is a weapon that no animal has ever thought of. Expedition Grizzly Hunt could have the ability to blow away a large Grizzly habitat, known as the Bear Cave, which is the Eagles main target in the war.
The project will use a special Eagle who will be trained to lay a modified egg, called the Atomic Egg, in mid-air over the target. The Atomic Egg, which will create an oversized egg shard radius when it smashes open, will be able to fly through the bodies of any animal near the explosion. The material inside the egg will have the ability to catch fire as it touches the ground, temporarily blinding anybody around looking towards the egg.
The Eagle leader, Hawkeye Truman, thinks of it as a way to defeat the Grizzlies in the most devastating way. But there is one problem. The Eagles do not know how to create this one of a kind weapon. Over a short period of time, Truman kills dozens of Eagles while testing different materials that would create the Atomic Egg. The final result is to use a material called Hawkanium. After testing the weapon, Truman immediately realizes that it is perfect and that it can knock the Grizzlies out of the war.
Truman gives a short speech before the launch of Atomic Eagle. With dignity, he says, “This is the day our war with the Grizzlies ends! This weapon that we have prepared will show every animal in the world that nobody shall ever mess around with us! Let us all hope that there will never be any more encounters between us and the Grizzlies. History will be made today, and today onwards we will continue on our prosperous path as a species.”
One week later, the Eagle, who is very hungry from the journey, is barely able to stay in the sky and lay an egg in midair. But luckily he is able to use his last chunk of energy and lay the Atomic Egg. Once the Eagle drops the egg, he dives straight into the water like a pelican trying to snatch a fish. Once the egg hit the ground, all the animals know the war is over. Caves are collapsing, the ground shakes rapidly, the sound of growling fills the air. It is undoubtedly the end of the Grizzlies, and the end of the war.
