lo, from the room with the broken ship at the end, I can go left into the boss room.
the ship kind of peeks into the room by slowly coming in from the left, before it super dashes to the left to be not seen again until i leave and reenter the room :-D
oh and in the room 2 left from the endroom(so left of bioss fight room), you can shortly see the ships pole before again the ship hyperdashes away.
this ship is even more shy than the rarest pokemon :-D
