mouse postman to deliver letter

Have you been to the Crocodile House?
Mr. Crocodile likes to read books,
But at home... Oops, there's water everywhere!

Have you been to Charizard's house?
Charizard's home is particularly warm,
Grilling sausages by yourself with flames is also very delicious!

However, it's best not to go to Mr. Snake's house.
Mr. Snake is so hungry that he can even swallow a car in one gulp!
Not to mention a tiny rat postman…
