Where did Ernest Aris draw his inspiration for the names? We can only speculate that Whiskers Rabbit with his blue jacket & black shoes is his answer to Peter Rabbit whilst Tom Kitten can only be a relative from
Beatrix Potter's Tale of Tom Kitten, which had been published in 1907.  Nutty Squirrel is too close for comfort to Beatrix's Squirrel Nutkin, (1903) whilst Freddy Frog owes something to Mr Jeremy Fisher (1906).  Mrs Cackle-Goose must surely be based on Jemima Puddle-Duck (1908), the tale of whom features a bushy long tailed gentleman who we recognise as Silas Slink Fox.  Dumpty Doo is a gentle parody of Puddle-Duck.  We do not have to speculate much on Willie Mouse as Beatrix's Timmy Willie (Mouse) featured in The Tale of Johnny Town-Mouse (1918).  Beatrix's husband, William, was referred to as Willie the solicitor, but perhaps all this is simply co-incidence as Ernest did also have his own Willie Mouse character who appeared in one of his first books. 

An Uncle Remus Tale entitled Brother Rabbit frightens Brother Tiger, gives a clue as to where Ernest drew his inspiration for Brother Rabbit (Ernest had illustrated Uncle Remus tales).  Dan Crow is one of the mischievous pseudonyms adopted in 1917 when he was accused of plagiarism. His cigarette cards include an elephant named Tiny Tusks who also featured in a story by that name that he had illustrated for Madeleine Collier.  They are both identical to the cub of the same name.  Jacko Monk also featured in the cigarette cards and whilst based on a character from Ernest's book A Bad Little Bear, published in 1918, he was to become Monty Monkey.  Squire Rooster Cockerel and Mrs Fussy Feathers can trace their ancestry to Captain Cockerel and Betty o' the Barn who had both featured in Ernest's book of that name.
