OK here is the intro tell me what you think.

Brain was unconscious on the lab floor. He slowly comes to and surveys the lab. He sees a white mouse jump out the window

Brain: Pinky?

Brain started running towards the window but the lab blew up flinging Brain through the doors into the street. Brain slowly got up to see a huge hole where the lab used to be. He turned around to find himself looking down the barrel of a gun. Before Brain could run he was grabbed and thrown into a cage. Brain got a better look at his captors, they where three huge felines in battle fatigues. They started to walk away from what remained of the lab when a single shot rang out. The feline that was carrying Brain's cage dropped it as he grabbed his hand and fell to the ground yelling out "Sniper!". Brain decided this was the perfect time to escape, his captures was too busy looking after their fallen comrade and looking out for that sniper. Brain ran towards the hole when he heard a whistling sound. The lab crashed back down into the hole filling the area with a dust cloud. Brain was able to just see the wall start to come towards him just then a dark figure came out of the dust and snatched Brain before the wall crushed him. The dark figure carried brain into a dark sewer. After running through the sewer for a few minutes they came to a small light room, Slappy was standing in the middle of the room. In the light Brain was able to finally see that the figure was Buster but he looked older, bigger and his fur was black. Except for an urban camouflaged skullcap and a rifle strapped to his back he had no clothes on. Buster gently put Brain down on the floor.

Buster: "The plan was to wait till Dr.Brain left the research facility before you blew it"

Slappy: "I saw Dr.Brain jump the rear window and was in the bushes when I blew it"

Buster: "I think you need your vision checked. I saw Dr.Brain still in there through the front window when you blew it."

Slappy clenches her fist and grows at Buster before marching out of the room into a dark tunnel. The sound of choppers and foot steeps from above fill the room.

Buster: "I knew they would come, it is hard not to notice a flying building, Slappy always uses too much explosives. They are most likely on their way to what's left of the research facility, once they pass you can go through that grate in there and pop up right behind them. They'll be too busy going through the rubble to notice you. I would take you but I still don't trust you. So farewell for now I got to get this dye off, I got to be on the set in the morning, Good luck!"

Brain made his way to the grate but he heard footsteps above. He quickly pressed his body against the wall. A light shinned against the other wall for a moment then disappeared as the footsteps got farther away. Brain waited for a second then climbed through the grate and ran through the night. The only though on his mind was finding Pinky.
