The face here reminds me of Bert of Ernie and Bert fame.
My kid thinks it looks like a Friar or Mr. Potato Head. A
larger bubble hanging down from a smaller bubble. Two
"eyeball" bubbles on the seam and a smaller nose between.
I also give him heavy eyebrows, tiny bubbles
semi-circling the top part of his eyes. On a good day, I
shoot googly eyeballs into the eye bubbles with the
straw.
