mouse postman ride rocket

Just like every morning, the rat postman goes out to deliver letters.
But today, he set off on a rocket!

Little Beep from the alien planet is looking forward to his birthday gift.
Mr. Whoa Whoa in Monster Land is waiting for a sticky, smelly package.

Don't be anxious, don't be anxious, please wait patiently,
The rat postman goes to the mountains and seas to achieve his mission!
