Isle of Tar
This is one of the few levels (along with Border Village and The Perilous Pit) that features the stone houses maybe built by Gnosticenes; in this level, there are two of them. The rest of the level is underground, consisting of several tunnels and caves, most of them with tar. In fact, there are five tar pits on the outside, and six other tar pits inside the caves. The lowest caves, especially the ones with the bigger tar pits, have distinct "tarish" backgrounds.
The goal of the level is to reach a ledge on the outside, right side of the level, with the exit. However, Keen cannot jump over some pits on his way, so he has to find a way through the tar caves to get back up to the exit. In order to do that, Keen has to get the red, yellow and blue gems. Along the way, he has to flip several bridge switches, jumping over falling platforms floating over the dangerous tar pits. With the blue gem, he can open a door to a tunnel in the right area of the level, which has a pole leading back up to the outside and to the exit.
- When you walk inside the two houses at the top of the level, the windows are in a different place compared to the outside of the house.
- There are a total of 28,800 points on this Isle. That means 5 Shikadi Sodas, 9 Three-Tooth Gums, 7 Shikkers Candy Bars, 2 Jawbreakers, 3 Doughnuts and 3 Ice Cream Cones (500 + 1,800 + 3,500 + 2,000 + 6,000 + 15,000 = 28,800). The largest number of accessible drops (Lifewater Oasis has more, but some are unreachable) is in this level: 95 in total. Two Lifewater Flasks are to be collected as well.
