Sailor Moon: Episode Five

Forgotten Doors

A door opens to a room with four doors, labeled A, B, C, and D, with door A having a keypad on the side of it. Here's the list of instructions.
There is a way to et your friends back, but you have to figure it out. Opening each of the doors does something different; one leads outside, one to the gem, one triggers the spell on the Sailor Scouts to end, and one releases a monster. Put these doors n order of escape, monster, gem, and spell and the monster door will deactivate, while the other doors open.
