Moskito's Nest
Moskito's Nest is the fourth and last level of Dream Forest, the first world of Rayman. It is made of 6 parts at the first time, and only 3 after that, because two of them feature Moskito and the last one is a Betilla stage.

Part 1
Only two cages will be possible to get the first time, as Rayman needs the Grappling Fist to reach one of them
Part 2
This dodgy level requires quick reflexes.
Part 3
Here, Rayman is chased chased by Moskito and must reach the end of the level before him.
Part 4
This level is slightly different in the PlayStation version, where the giant trunks are missing. Also in the PlayStation version, this is the only level along with Bongo Hills in Part 6 and Eat at Joe's at Part 4 to not have any cages and not involve a boss.
Part 5
Part 6
Betilla gives Rayman the power of the grappling fist.
