Here's a retail display for the Sonic Bath Balls!
These are blind-bagged bath enhancement items that make the water scented & fizzy. In this case, the scent is said to be mint. Each aqua blue colored ball inside the packages you see here has a surprise: a 'little cuite' style Sonic figure. The figure is revealed once the ball dissloves into the bath. So, it's a toy AND a fun bath time item at the same time.
The Sonic art for the display has him in a tub, obviously smelling the nice scent of the product. The bottom has the price. The 'rubber ducky' looks a bit like it has been melting, however. What does the vertical pink headline say? These appeared in early 2017.
