Uh no , uh personally as a Marketing Expert I don't believe that ,
because whatever companies  they launch their products in the shape of fruits , they give a range of products , a range of shapes , like if we see , look at the smallest thing , toffee chocolates , they give a variety of different things.
Mm-hmm.
Some children like to buy banana shape , some apple shape , some even pineapple shape , some orange shape.
