Name all the levels on original Lemmings that contain a trap that only appears on that level.
Rendezvous at the Mountain: the rock squisher trap
Lend a Helping Hand...: the spike traps on the walls
Going up...: the electrode trap
Poo Wee Creatures!: the molecularizer trap
Q: name all levels in ONML that have 4 entrances. [Appropriately enough, there are 4 such levels.]
