"Guys?" Finn called down the dark halls of the Condor. This was weird, we never turn the lights off in the day and the engine isn't running, Finn thought to himself.

There was a sudden scurry behind him and it made him whirl around in a hurry. "Radar?" Finn called but nothing replied back. "Okay guys, you've made your point!" he shouted quite angry this time. He hoped that his team weren't playing a trick on him, he didn't like being pranked. That was his job!

Just then, there was a groaning behind him and Finn turned round and to his horror, he saw a zombie like creature staggering towards him. It had no eyes, its clothes were in rags, its hair fell down around his face and its skin was a rotten and chunks of it were falling off.

Finn screamed his lungs out, he had never seen such a terrifying creature before in his life! Still screaming like a girl, he ran for his life to his room to get away from the zombie but when he got to his room he had another shock.

There on his bed was an over-sized rat with blaring red eyes, black fur, a bony tail and fangs with dripping saliva. As soon as it saw Finn, it let out a piercing shriek that echoed off the walls. Finn screamed again and ran for the bridge and he found yet another shocking surprise.

There were three more zombies there and these looked more terrifying than the last one. The first two looked the same; they both had no hair, just a scaly scalp, they had one eye missing each and one eyeball was hanging off by a thread with blood dripping down his face. They wore the same rags like the last zombie did and they had fangs that stretched down to their chin. The one in the middle seemed to be the boss of them. He had messed up hair, claw like fingers, ragged clothes, glowing green eyes and mouldy green skin. Finn had never been more scared in his entire life. He screamed so loud that the people on Terra Rex could hear him.

The green eyed zombie raised one clawed finger and pointed it at Finn. As if following and order, the pair staggered forward, arms outstretched. Finn started backing away but to his horror he saw that the other zombie and the rat had come back.

Now they were all closing in on him, their arms reaching for his head. Finn let out one more scream and the zombies stopped. The leader lowered his head to Finn's and said, "Trick or Treat" in a mocking voice. "Huh?" Fin said raising his head in confusion looking the zombie right in the eye. They had lost their glowing green colour and had just gone to a normal green colour. "AERROW!" Finn screamed, not in terror but in anger. All of the zombies, including the rat backed away and started laughing their lungs out. They then pulled Chroma crystals from their pockets, one for each of them and they then dropped them on the floor.

Instantly, in a flash of light all of the zombies turned back into the team. Junko started to laugh like a maniac, Stork actually chuckled for the first time and Aerrow and Piper laughed like made too as did Radar. "Not funny!" Finn said folding his arms and pouting like a toddler.

Everyone managed to stop laughing and they all raised their arms and said 'HAPPY HALLOWEEN!"
