Source: Kellogg's </Td> </Tr> <P> Froot Loops is a brand of sweetened, fruit - flavored breakfast cereal produced by Kellogg's and sold in many countries . The cereal pieces are ring - shaped (hence "loops") and come in a variety of bright colors and a blend of fruit flavors (hence "froot", a cacography of fruit). However, there is no actual fruit in Froot Loops and they are all the same flavor . Kellogg's introduced Froot Loops in 1963 . Originally, there were only red, orange, and yellow loops, but green, purple, and blue were added during the 1990s . Different methods of production are used in the UK where, due to the lack of natural colourings for yellow, red and blue Froot Loops are purple, green and orange . and the loops are also larger in size . Although the marketing side of Kellogg's sold the idea that each individual loop color was a different flavor, Kellogg's acknowledged all share the same fruit - blend flavor . </P> <P> Toucan Sam has been the mascot of Froot Loops since its first appearance . Toucan Sam is a blue anthropomorphic toucan; the colors of his bill correspond to the three original froot loop colors . While most toucans have a good sense of smell, he is portrayed as having an uncanny ability to smell Froot Loops from great distances and invariably locates a concealed bowl of the cereal while intoning "Follow my nose! It always knows!" or "Follow my nose! For the fruity taste that shows!" </P>
