Girl Born in January Since she was born early in the year, she is more developed than her peers and speaks very well. She is full of curiosity and never stops asking questions. She is a chatterbox who tells the teacher every little detail about what happened at home. Her trademark is her chubby cheeks because she loves snacks so much! As the oldest, she helps her friends like a big sister, but Seoyun is still a baby herself! Actually, she's the biggest crybaby in the Sprout Class! She can be quite greedy, so if a toy is taken away or she gets just a little bit less snack, she quickly gets sorrowful and bursts into tears.

Boy Born in February He has a very pretty face for a boy. However, he is actually a mischievous prankster with overflowing energy! His eyes sparkle whenever he sees cars or robot toys. Because he is so active, he often runs around the classroom holding toys, so he requires constant supervision. He speaks so well that he sometimes catches the teacher off guard! He is a bit of a picky eater, so if you encourage him to eat something he hasn't tried, he might talk back, asking, "Did you eat it, Teacher?"

Girl Born in April She speaks well, but she is very shy and doesn't talk much to strangers or people she isn't comfortable with. The words she occasionally whispers are incredibly cute! She enjoys quiet, seated play. She especially loves drawing and puzzles. She strongly resists when it's time to clean up or when a friend asks to borrow her toys. She has a level of focus and stubbornness where she won't easily stop once she has started something.

Girl Born in August She is just starting to speak. Currently, she can say two-syllable words like Mommy, Daddy, Yua, Yummy, and Cookie. Her vocabulary seems to be growing steadily. She has a gentle personality and rarely cries, but she becomes more active than anyone during snack time. The first word she ever said was "Yummy!" She is known for bringing snacks every morning. Even though she loves eating, she is happy to share when her friends ask, "Can I have one?"

Boy Born in December He understands what is said but cannot speak well yet; he is at the stage of mimicking adult words bit by bit. He is smaller than the other children and very shy, making him a 'Teacher-follower' who trails behind the teacher all day long. He always carries his comfort doll 'Gomi' and never lets go of it no matter where he goes. He is a very picky eater and bursts into tears if the teacher or his doll is out of sight, but he is a cutie you can't help but love. It seems like the other kids see Onew as the 'baby' of the group...?
