咧 = 口 + 列 : Li Qingzhao (li) is on a date with archangel Gabriel (列) in the elevator's living room (e3). She feeds him mandarins (口) and he's too shy to tell her that he hates mandarins. Instead he draws back the corners of his mouth (咧) while chewing on the mandarins with a wry grimace (咧).

嘴 = 口 + 觜 : Zapatista Zebra (zu) is roaming the Eiffel Tower (ei3) to look for food. Because the floor is full of horns (觜), he is wearing safety boots (觜). With his lips (嘴) he is forming a long beak (嘴) to look for mandarins (口) between the horns.
