"Nikki Nikki Tembo No So Rembo Oo Ma Moochi Gamma Gamma Goochi" is the name of a little Chinese boy in a story called "Long Name No Can Say" narrated by Paul Wing. It was available as an RCA Camden recording when I was little - circa mid-1940's. It seems that this same story has been retold many times in many variations, subsequent to that time period, which is perhaps the origin of the "Tikki Tikki ..." variety.
