Our hilarious "Proliferating" Penguins Mug depicts five monogamous penguin couples having a fun time perpetuating the species and then some. These fun five couples wrap around this 4" tall ceramic coffee mug.  This original penguin gift shop classic frolicking mug is certainly the frisky penguin mug that all others are judged by. Simply a timeless and great gift for the adult penguin lover with a sense of humor, that thought they already had everything. Made in the USA. Microwave and dishwasher safe.
