The Big Building of Doom

You start in front of a bunch of former humans and one former sargent. Preferably switch to your fists (1) and punch them using your chainsaw attack (ALT FIRE). There are a few pink blobs standing on nearby crates. Use your pistol (or shotgun, if the Spyro basket gives you that kind of ammo) to shoot the blobs before they can go flying at you. Go behind the crates to find a few Quartz Flasks and a Boots of Speed. Jump up the crates, keeping an eye out for the Golden Blob, a stupid blob that shoots rapid fire at you.After getting into the air system, shoot the two Sewer Blobs and grab the super shotgun. Next, jump down into the room below and shoot the Sewer Blob. Turn left from the fall and open the door behind the Oswald's Helmets. Pick up Princess Bubblegum's Umbrella and the blue key, then exit the rooms. You will be in a hallway with a angry hammer bro. Watch out for him, shooting around the corner before he can shoot a hammer at you; Be careful as these explode. Once he dies, go outside and kill the former human and former sargent. Follow the stone path to a hole and fall down it. It's a secret area: inside, you'll find rings and Kai-lan's Dinosaur Helmet. Hold down JUMP and jump back up the hole, then follow the path back into the building. Enter the first door you see on your left; this door leads into a room with lava and a few former humans. Kill them with stealth, then run across and use your blue key you got earlier on this door. It should open and allow you to proceed down into the depths of this big building.Once down here, kill the three Sewer Blobs and then head down the curvy path to a floor with stripes. This floor is dangerous; It has crushers that randomly fall everywhere, so save here before attempting to cross it and collect all these rings! After crossing it safely, turn right and pick up the Railgun and destroy the Spyro basket. Open the door and aim your Railgun (7) straight down the line of enemies, then shoot it. Immediately save and switch to a better weapon like the Rocket Launcher or Super Shotgun. Shoot the Demons and Imps, being careful of the Demon's explosions. Next, grab the Quartz Flasks and don't pick up the Invulnerability yet; enter the room and pick up the yellow key and the invulnerability in that room. Four nearby rooms will open up, and Pikachu, Jirachi, Former Humans, Baron of Hells, and many others will come out. Shoot with your Rocket Launcher or Yoshi (aim at the Game Boy Camera Face, the creepy drawing, as this is its weakness; not killing it will cause it to resurrect the former humans.) Run out of the room and grab the second invulnerability as the current one runs out (this is why it was a good idea not to pick it up). If done fast enough, all enemies should be dead by the time you're out of invulnerability time. Next, back out with your newly earned key and activate the switch in the middle of the crushers. You'll appear on a lift slowly rising to the surface. Enjoy the ride.Once you reach the top, run on top of the wall and enter the building ahead. You'll reach a ship. Get on it to complete the level.
