Pocoyo
Nina is another human character who is introduced in the 4th Season episode of the same name. She is a young girl similar to Pocoyo (likely younger than him) who has red hair, wears a lime green hoodie with two antennas, lime green shorts, and lime green shoes. Like Pato, She greatly loves plants and nature. She naturally speaks mostly a form of gibberish with Japanese or Spanish accent, but can also speak fluent English, though not as much as Pocoyo. She appears to be very fond of Pocoyo, always playing together like siblings. One image shows Nina kissing Pocoyo's cheeks, implying that they have a relationship. Her name resembles "niña", Spanish for "girl". Thanks to her robotic pet called Roberto (pronounced Roh-bear-toe), it has the ability to shrink where anyone can be shrunk as well. She replaces Loula's bit in the title sequence (except in her debut appearance and the episodes where she's absent). She is voiced by Noela Rodriguez.
