The little girl that the doll’s-house belonged to, said,—“I will get a doll dressed like a policeman!”

In 1971, Hunca Munca and Tom Thumb appeared in a segment of the Royal Ballet film The Tales of Beatrix Potter, and, in 1995, the tale was adapted to animation and telecast on the BBC anthology series The World of Peter Rabbit and Friends. One morning Lucinda and Jane had gone out for a drive in the doll's perambulator. There was no one in the nursery, and it was very quiet. Presently there was a little scuffling, scratching noise in a corner near the fireplace, where there was a hole under the skirting-board. Then there was no end to the rage and disappointment of Tom Thumb and Hunca Munca. They broke up the pudding, the lobsters, the pears and the oranges. The little mouse’s name was Tom Thumb. A minute later, Tom Thumb’s wife, Hunka Munka, popped her head out too and when she saw the room was empty, she and Tom squeezed through the hole and went over to the coal box by the fire.So I may be overdosing a bit on nostalgia tonight, but I'm feeling oddly sentimental and wanted to share my thoughts.

When two naughty little mice discover the door to the beautiful dolls' house ajar, they just have to tiptoe inside and have a look. The temptation to try the delicious looking food in the dining room proves too great however, and chaos ensues when they discover that it will not come off the plates! Jane was the Cook; but she never did any cooking, because the dinner had been bought ready-made, in a box full of shavings. While Tom Thumb was up the chimney, Hunca Munca had another disappointment. She found some tiny canisters upon the dresser, labelled—Rice—Coffee—Sago—but when she turned them upside down, there was nothing inside except red and blue beads. Tom Thumb and Hunca Munca went upstairs and peeped into the dining-room. Then they squeaked with joy!One of the most striking things about the tale is that the mice are "bad" - transgressive, as the OP notes. They are not merely bad in their destruction of the doll's house: there are also suggestions they are bad parents. They live in a squalid hole and have a large number of children. In contrast the doll's house that they enter is clean, polite and refined. The response of the mice to this is impulsive aggression and theft. The things they choose to steal are also instructive: they take food and bedding, but reject more refined objects like a bird cage and a book case. It is not hard to view this as a metaphor in which the mice represent the working class "vermin" and the dolls a more genteel middle or upper class society. On the other side of the replace was the beautiful doll’s house. The two mice tip-toed cautiously across the rug in front of the fire to take a closer look.
