终极

终 = 冬 + 纟 : Julian Giant Squid (zhu) and the silk worm (纟) are eating udon noodles (冬) in front of the engine ((e)ng1). After a while into the dish they accidently both suck on one end (终) of the same noodle and eventually kiss.

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.
