The piano theme played in the end credits was played by the series star, Bowie Bundlie, when he was eight years old.
Remy Bear was originated in China where it is wildly popular. There it is known as "Xiong Xiao Mi" or "Our Friend Remy".
A few years after the original show ended its run, Our Friend Xiong Xiao Mi got a revival series called A Little Artist Xiong Xiao Mi, where Xiao Mi now gets help from the Magic Brush to draw certain animals and other objects to help he and his friends resolve that episode's conflict. The revival series is intended to teach children how to draw said objects.
Our Friend Xiong Xiao Mi, also known as Our Friend Remy Bear in other regions, is a Chinese animated children's television series which was created by Xiong Xiaomi (Beijing) Culture Communication Co., Ltd. It aired as a segment on the children's show Zhi Hui Shu ("Tree of Wisdom"). The series began airing circa 2013 and ran for 52 episodes.
The original show is available in both Chinese and English on Miao Mi, a website meant to teach children the Chinese language which hosts several Chinese cartoons to help children practice learning the language.
