Keroleen's is friends with Kerokerokeroppi. Her birthday on January 21st.
In her Sanrio Timeline artwork, Keroleen appears as a frog girl with light-brown pigtail hair and red ribbons on each side. She wears a red dress with a white polka-dot pattern and black tie. She has two pink circles on her cheek.
Keroleen is a kind girl and acts as a peace-maker after an argument or a fight. She is passionate about fashion and collecting new clothes. She can rarely be seen wearing the same clothes twice. Her favourite outfit is her polka-dot dress, and is learning about Donut Pond cooking from Keroppi's mother. She can "leapfrog into a new costume before you can say 'ribbit'".
