苦衷

苦 = 艹 + 古 : Karl Koala decided to repent for his sins and retreated into a cloister inside the space station. There he leads a very simple life full of hardship, e.g. he gave up on eucalyptus and just eats very bitter artificial lawn.

衷 = 中 + 衣 : Julian Giant Squid (zhu) is feeling very strange lately. As he is passing in front of the engine ((e)ng1) has some weird inner feelings (衷). He doesn't realize though that he forgot is dart board (中) in the pocket of his kilt (衣). It is the bulky dart board which is making him feel uncomfortable. (Look, the dart board is hiding in the kilt: 衷)
