Don't worry, I haven't forgotten about these two!
In 2016, I made a New Year's resolution to create a short animated film from start to finish within a year. And these two would be the stars.
I had a story and plenty of gags. All I needed was a name for the two...I settled on Kouka & Bibi.
I named them after the "bouba/kiki" effect. Like the bouba and the kiki, you're never completely sure which one is which.
