Sunil Nevla is a mongoose with a talent for magic. Usually, his magical tricks come in handy and can really wow the crowd, but he sometimes messes up, and apparently explosions are semi-common of his tricks. He is best friends with Vinnie Terrio.
Sunil is a very crafty mongoose who loves magic. He is often shown to practice it, or may use it when it would come in handy. However, he's also very cowardly and even admits this as his most common of all faults. The others care deeply about him and he knows this, but sometimes it isn't enough to make him face his fears or worries. He also dislikes the thought of love, but this is stopped temporarily when he is put under a love spell (by Sugar Sprinkles), and falls in love with Pepper. At the end of the episode however, Sugar Sprinkles reverses the spell (due to the boys in disco suits, in which she says "Okay, that's just wrong."), and he drops Pepper (who he was holding) in disgust.
Sunil panics very easily, but when cobras come up (real or imaginary), he strangely turns very strong and competent and is able to do the job right. Blythe and Russell use his natural hatred of cobras to give him the confidence to help rescue the remaining pets (Zoe, Minka, Penny Ling, Pepper and Vinnie) from their imprisonment within the Largest Ever Pet Shop.
Despite his timidity, Sunil reveals to have a pretentious side, such as when he boasts about Jasper getting his voice correct when it was an inaccurate deep voice in Commercial Success and he tries to prove himself to be an excellent painter in Two Pets for Two Pests.
