The Dangerous Descent (Unlocked by Challenge Key from The Wedding Reception)
This is a mini-game in which you will die eventually. Jump through the holes of the platforms in order to avoid the poison gas below and above you. As a rule, try not to go too low: sometimes two holes come right after each other.
Wobble Poles: (Unlocked by Challenge Key from The Wedding Reception)
In this minigame you'll have to race to the finish within 30 seconds! You'll come across plenty of wobble poles, which make for the upper path. Needless to say, the upper path is faster and holds more score bubbles. The score bubbles are nice to score points, but they also significantly improve your score due to their time-stopping ability. Unfortunately for you, the upper path is also more difficult. If you fall off somewhere, it doesn't necessarily have to mean your death. You can continue the lower path - and deal with a lesser score.
Bubble Labyrinth (Unlocked by Challenge Key from The Darkness)
Use the sponges to make your way around the labyrinth, and don't touch any hot coals twice. The best way to score major points is to finish this level as fast as possible - looking for score bubbles will not improve your score more than racing quickly.
