GRAND CHASE VS. ANGRY BIRDS!
After being tired battling thanatos the grand chase gang would like to go to vacation. And they had chosen the great spot… KERRIE BEACH, since there is no monster that dwells in there and the beautiful sun shines at the beach. So they asked arme to teleport them to their chosen destination… After that the vacation begins. Lire and Ryan go to the forest, while the others our sunbathing and swimming. While Lire is in the forest she had seen 5 eggs in a nest without a bird guarding eat, so she immediately called Ryan to carry it. And when they reached the beach everyone wanted to cook the egg. When Amy is about to cook the egg then there is a black round bird that flew to her and exploded. Then the others heard it and panicked. But Elesis stood up and attack the birds that where attacking them. When the birds almost hit her she strike it with her sword. But then something bigger is coming to her and before she had run she was hitted. While Elesis was badly hurt the others were fighting the bird as well. When arme is casting fireballs to the bird a yellow triangle bird appeared and went fast to her and she was hit before she can teleported, and lass got angry seeing that armed was hit. So he attack all the bird with a shuriken, but unluckily a blue one appeared and multiplied. Lass don't know which one will he attack first and then he was hit. Then the white one appeared and attacked grand chase with eggs, luckily the lire and mari wasn't hit by the birds. So mari is trying to build something when a black bird walked near her explode(more like a sneak attack). And so the remaining member is lire who is trying to figure out what to do, then she remembered the eggs. So she took the eggs from amy who had been fainted and give it to the birds, and she explained. The birds understand her and, stopped attacking them. While lire is happily going back to the gang she noticed something. She is the only survivor! THE END
