Could we see a picture of the quilt? I did see one quilt that had a big "paint" looking splat on it that really looked cute. This site has some cute ideas

Or you could applique some toys or teddy bears or flowers, stems & leaves. If you haven't already quilted it, then just remove that block and insert a new piece of fabric.
