Hausmeerschweinchen
The seventh and last rhyme is a limerick about an "amiable guinea-pig" (the first guinea pig in Potter's work) who brushes his hair back like a periwig and dons a blue tie. The verse is accompanied by three illustrations depicting the guinea pig in various stages of coiffing and dressing. Guinea pigs would have their own story told in the tale of Tupenny in Potter's "The Fairy Caravan" of 1929.
