叶酸

叶 = 十 + 口 : Maud Younger (y) practised a trick shot all day in the elevator's bathroom (e4). She's now able to throw a leaf (叶) high in the air, then quickly throw a mandarin (口) and beat the mandarin with a cross (十) like a baseball with a bat so that the mandarin rips a hole right into the leaf.

叶 = 十 + 口 : You could see the cross 十 as the leaves 叶 of the mandarin 口.

酸 = 夋 + 酉 : The rooster (酉) and Susan Saint Bernard (su) where once friends, but recently they haven been fighting over a lover. Because they are both wuxia (夋) superheroes, they have been fighting for three days in front of the anthill (an1) without determining a winner. Finally they decide to settle their sour (酸) dispute and share a tart (酸) tarte to renew their friendship.
