 The nature artist and the fantasy artist in Potter are at odds : the mouse , the toad , and the insects share the same habitat but there seems no logical reason for the mouse and the toad to be humanised while the insects remain their natural selves . Logically , they should be humanised , too . While the toad is an invader like the insects , he does Mrs. Tittlemouse the service of ridding her house of the bees yet is inexplicably excluded from the party , an affront to the reader 's sense of social right and wrong . It is possible Potter 's carelessness in the details of Mrs. Tittlemouse can be attributed to a desire on her part to simply display her ability to draw from nature or to her interest in book production being supplanted by a growing interest in farming and local life and politics in Sawrey .
