Bugs Bunny & Taz - Timebusters (GBC)

Bubble gum:
When taz is chewing the bubble gum, blow it up until it just starts to go red, then stop for a couple of seconds and press the X button to inflate it again to the largest size.
This will definetly get you to those hard to reach places. Also make sure Bugs gets the gum for you, while you are at the point of elevation.
