Dib lifted his head from his notebook again, looking at Zim's chair. Empty. Why was it empty? What was Zim up to? Is he in skool at all? Dib raised an eyebrow and looked back at his notebook. The only good thing about Zim not being here is that he got to miss the test. Dib finished it early and had a lot of free time, so he pulled out his notebook and started to doodle. Dib sighed at his work.

The only thing that was on the page was ghost Zim, taking up the whole page. Dib remembers the day Zim and his robots came into his room and dressed up like ghosts to frighten Dib. It turned out that Zim told Dib to call Mysterious Mystery's and to make him feel embarrassed on live TV. Zim likes to call that plan, 'Day of Da Spookies.'. Dib rolled his eyes and started to shade in Zim's spiky hair. Dib even remembers what Zim looked like. He had spiky hair, his hands and face was white, he wore fingerless gloves, t-shirt and his normal trousers that where black. His eyes where purple and wore huge boots. The boots helped him fly in the air.

Dib put his pencil down when he finish shading. What should Dib do now? Everyone still had 10 minutes left… Hmm…

Everyone, even Dib and Miss. Bitters jumped and looked at the class room door when they heard a huge bang. Zim came running in and closing the door behind him, panting and covered in black smoke. Dib raised his eyebrows and looked at everyone, who just got back to their test. Miss. Bitters raised an eyebrow at Zim and hovered over to him. "Zim? What are you doing?" She wondered, Zim finally calming down a little. "S-Sorry, Miss. Bitters. Something happened back at home…" He replied, sighing. Miss. Bitters sat back at her desk and Zim slowly sat in his chair. "Well, there is no point in giving you the test if we only have 8 minutes left and after this we have home time… so do what you like, since you will never get the chance to do it again."

Dib looked at Zim, who just nodded and banged his head on his desk and closed his eyes. Dib raised an eyebrow and noticed at the side of Zim's head, was a cut and had blue blood. Blue blood? Dib smiled and stood up on his desk, pointing at Zim. "Look, everyone! Zim has blue blood! Look at it!" He shouted. Zim turned his head and opened his eyes a little, looking at Dib. Zita moaned. "Dib, would you shut up? I need to finish this test, because if I fail, you're the one who's going to have blue blood!" She shouted, throwing a pencil at his head.

Dib rubbed his head and sat back in his chair, watching Zita finish her test. Miss. Bitters nodded and Dib packed his notebook away, waiting for the time to go.

Rrrrrrrrriiiiiiinnnnnnngggggg….

"Where have you been?" Gaz wondered, crossing her arms and watching Dib walk up to her. "I had to say sorry to Zita for something I did… and I was listen to Miss. Bitters saying to Zim to clean up the mess he made in the hall way…" Dib relied, walking past Gaz and bringing his backpack close to him. Gaz looked around and noticed that the hall way was black and the when they reached the huge doors, they was not there. All was there was a huge hole on the wall. "Hmm… I wondered what Zim did…" Gaz wondered again, pulling out her G.S.2. Dib nodded and turned around, seeing Zim with a mop and cleaning the walls. Dib smiled a little and looked forward.

Zim looked at Dib and stopped cleaning, setting the mop down for a second. He reached up to touch his head and pulled back, still seeing blue blood. He pulled out some cloth and dabbed his head, still looking at Dib and watching him leave. He pushed the cloth back in his PAK and picked up the mop, cleaning the wall again and hearing children scream and laugh as they leave the skool.

"… and he had blue blood, Gaz! Blue. Blood! I mean, no one has blue blood!" Dib shouted, raising his arms and looking at his sister. Gaz lifted her eyes off her G.S.2 for a second and then back. "I got blue blood…" She muttered and leaving Dib confused, which made her smile a little. Dib looked forward again and opened his mouth again. "Yeah, but-!" He started but Gir came running up to him and jumped on him. "Mary, help! Have you seen master? I give him this to help him! Or he may get small like a peanut and I would eat him all up! Mary!" He shouted and pulled out an empty jar. Dib rolled his eyes.

"Yes, I have… He is at skool…" He replied, getting up and holding Gir up. Gir laughed a little and ran to where skool was. Dib raised an eyebrow and looked at Gaz who just walked ahead.
