If the Smurfs mutated into oval blobs......
...they might look like this.
Barbapapa is both the title character, and name of the "species" of said character, of a series of children's books written in the 1970s by Annette Tison and Talus Taylor, who resided in Paris, France. The books were originally written in French, and were later translated into many languages. As short cartoons of a length of only five minutes, they reached a broader audience via TV.
Barbapapa himself is a generally pear-shaped, pink shapeshifting blob-like creature who stumbles upon the human world and tries to fit in. After various amusing adventures, he comes across a female of his species (more shapely, and black-coloured), named Barbamama. They produce seven children, known as the Barbababies, each a different colour.

I must have been really thirsty to pick up this character. I quickly gave it to a co-worker who squealed, "Kawaiiiiii!" (Cute--カワイイイイイ)
