Monty Python's Complete Waste of Time/The Brain

The brain is the hub that lets you go to different lobes of the brain.

The Secret to Intergalactic Success
The brain is the last area of the game that you need to complete.

Once all lobes of the brain are flashing, a new icon appears in the top left corner. Click it to start the final minigame.

The final minigame is Simon says with the brain lobes. Lobes will flash in order and you will have to repeat the pattern by clicking the lobes. The last round is a freebie, just keep clicking lobes and you will win.

Now, if this was 1994, you could've entered the competition. But it's not so this was all a complete waste of time.
