Down the Tubes is the third level of the Factory area of Pac-Man World. This level is similar to the previous level, Under Pressure, and can be completed very quickly if Pac-Man does not wish to look for collectibles. However, it is where Pac Jr. is located, and therefore Pac-Man must find the key (also located in this level) and free his son if he wants to defeat Toc-Man. Finding the key and freeing Pac Jr. is not so simple here. The level is filled with obstacles that were found in Under Pressure, but they are more numerous here, so Pac-Man must watch out. If you don't have at least 10 lives, be prepared to restart the level multiple times.
