This little mushroom plug measures 3.5 inches, with a 1.5 inch long and 1 inch wide (4x2.3cm) stem and a 2x1.5 inch (5x3.5cm) bulb, and a 5.5cm diameter log for a base. It's made of a squishy shore 0050 silicone, with textured yet easy to clean gills around the bottom of the bulb.

It's available in Fool's Blue or any marble of two colors. Any selection of Fools' Blue and another color will be Fools' Blue only.
