Rhaimie is a writer and Rizal is a self-taught artist. Together they published the children's book Tim's Adventures (Pengembaraan Tim) and Otters in the City (Siri Biodiversiti Ungu Pen: Memerang di Kota). The brothers also discussed how they work together, seeking ideas and inspiration from different mediums to publish children's books. We also talked about augmented reality in books and bringing Singapore's unique animals and culture to the international scene. Their books can be bought at https://ungupen.com and are available in 2 languages. Follow them at Instagram https://www.instagram.com/tim.and.friends/
