For me, the funniest part was when they were in Treno, and the man with many arms wanted to get back at Amarant, and he saw Eiko with him and thought they were friends. So he planned to kidnap Eiko (I think). When he tried to get Eiko to go with him, Quina appeared, and he thought he/she was Eiko's body guard hired by Amarant. I thought that part was so funny- and cute!
