极其

极 = 及 + 木 : As Joan of Arc (ji) and Yuwen Huaji (及) pass over the north pole (及) at Christmas just inside the space station's entrance (Ø2) they decide to celebrate this moment by having a little contest. Between them there is a rather large Christmas tree (木) and they decide that whoever climbs to its top (极) first is the winner.

其 = 目 + 八 : Looks like a watchtower. The Queen of Hearts is on lookout on the watchtower just inside the space station's entrance. The Eye of Providence helps her to look out for intruders. They also spread some eight balls for possible intruders to trip on.
