Up Next: BRB flies back to preschool with Kambu

It's been almost 20 years since Barcelona-based BRB Internacional has touched a preschool project, but the target demo is back on its radar for Kambu. The designs inspiring this 104 x five-minute CGI series come from a Korean studio called Chako, and they center around an expressive and naive dog who delivers airmail to the inhabitants of Mystery Island. Along with his sidekick, an affectionate but anxious little lovebird named Mayday, Kambu's mail runs are all about spreading good news and cheer through things like greeting cards and gifts. But he's often foiled by the backwards and upside-down nature of Mystery Island, which is inhabited by incongruous species like tiny elephants, giant ants and cowardly ghosts.
