邋遢大王奇遇记

There is a little boy nicknamed "Messy Prince," who is extremely slovenly and disregards hygiene, believing that "what doesn't kill you makes you stronger." One day, the Rat King, seeking to conquer humanity and dominate the world, decides to find a human test subject for his bacterial weapon. The Rat Kingdom's spy sets his sights on Messy Prince, as he is the only one who would eat unclean things. Thus, after drinking orange soda drugged by the rats, Messy Prince shrinks to the size of a rat and is tricked by the rat spy into entering the Rat Kingdom! Once in the Rat Kingdom, Messy Prince truly regrets his ways and wants to go home, but he is helplessly locked up. Fortunately, his friends, the kitten and puppy, replace the experimental serum prepared by the rat scientist for him, allowing Messy Prince to narrowly escape disaster. Will Messy Prince ultimately manage to flee the Rat Kingdom?
