I don't think so. It's not just the simple style, which is accurately reproduced. It's missing and incorrect punctuation.

>“I like puzzles” said Toad. “Can I try them?”

Should be

>“I like puzzles,” said Toad. “Can I try them?”

That's how it's punctuated in the books, as far as I can see, and is standard for that type of dialogue. there are several of these omissions.

>“You cannot. These puzzles are for little machines, not people” said Mr. HuggingFace.

>“They could get up to mischief” said Frog.

>“Do not worry” said Toad “I have put each of them in a sandbox.

These don't seem intentional. also:

>“You must be very busy.” said Frog.

should be a comma, not a period.
