The trio of Pygoscelis penguins from the water park try to figure out how to sell their excess of penguin cards, eventually settling on creating a concentration game with them, which becomes a hit. Meanwhile, Penguin ends up having to date all the Penko sisters equally, but still has trouble telling them apart. Sasako suggests he give the sisters differently coloured ribbons to better identify them, but it backfires when they decide to trade them with each other.
