''You're.. not blue.. You're like the opposite of blue. Your scent is soft and firm and it reminds me of something sweet like honey.. Something nice.. Something happy..It's just something that I will go to every day. It makes me smile!'' (Fennel to Cosmo, about his feelings for him, episode 8)
Fennel is May's seventh vessel. He is a blue gray tabby tom-cat with blind blue eyes.
Fennel's problem is that he is afraid to tell his friend (Cosmo) he is in love with him.
