fun story. missing some punctuation, though: primarily commas at the end the first parts of split dialogue.
>“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.
