Starting Out In The Sewer

Don’t forget to hold your nose!
After travelling down the pipe and emerging in the sewer you can make a quick save using the save block or jump into the water to progress deeper down the tunnel.
Head to the right side of the first area and you’ll find another pipe. Jump onto the pipe and press ‘A’ to travel to the next area.
You’ll appear in the second room, surrounded by more stone walls. To continue onwards you must run to the left of this chamber and take the next pipe out of the room, as shown in the screenshot below.

When you arrive in the third room, you’ll be quite high up in a flooded chamber. From your starting point jump to your right and land on the thin slab next to the archway. A rat enemy will be patrolling back and forth on the next slab down. Either touch the rat to enter combat or jump over the rodent to arrive at the green pipe, as shown below.
