Defeating the Dragon
Go to the one weird Lost In Time level. Get the clock and go back in time near to where Sam the sheep dog is found. A Dragon should be in front of you. Go back to the future, and the Dragon will go with you. Sam will know that the dragon will try to burn the sheep. Sam will run down to the Dragon and punch him away. This trick will not work if you are not in Sam's area.
Defeating the Red Hairy Monster
Leave the sheep in the Annex and walk into room where the Red Monster (Sherman) is located. Immediately speed past the Monster on the left side. Sync your jump with his, and jump towards him and over his ring. He will chase you, but do not let him squash you. Speed around him in tight circles until he gets dizzy and falls down. If you do get squashed, just run away from him until you pop out of it then try again. After he falls, quickly grab the sheep and lay him on the button. When the quadra-platform cools, jump on it and continue to jump onto the platform on the right until it spins clock-wise enough times to lower the lens over the torch (and shine a beam on the Red Monster). Repeat this step two more times with the other lenses until Sherman falls across the lava and creates a "bridge." Get your sheep and walk over him to the goal.
Hidden Back In Time level
To enter the hidden level in Back in Time, enter the Back In Time level door from the opposite side.
