Defeating the taxi cabs
When outside Blot Alley at Club 15, hit the cabs on the front and the hood will break off. When this happens, jump on the button to stun it, then paint or thin the blot.
Have Oswald zap the Beetleworx until it becomes stunned. If you are near enough, the view will zoom in slightly and Oswald's remote will emit blue waves. Twist the remote slowly until the waves change to bright green. Hold it in position until you are prompted to press a button. Note: This will have to be occasionally repeated.
