Battletoads/Turbo Tunnel

Welcome to the Turbo Tunnel, known by many players as the hardest level in the game! You'll need lightning-fast reflexes if you want to make it through the tunnel.

The Mutant Rat Troop
At first, you'll come across a mutant rat. Take him out by knocking him into the floor, and kicking him until he's gone. You'll find a lot of these rats while going through the tunnel: they might take some health points, by they will be the least of your problems. After fighting about 9 rats, you'll come across a pair of turbo bikes: take one to start real challenge of the Turbo Tunnel!

Turbo Bike Riding
Now some people have problems jumping from platform to platform. That's because they're jumping from the middle or top. You have to jump from platform to platform at the bottom of the screen.
