Despite having eaten all of the dish, the serving size was indeed small, which left him very unsatisfied. This time, he came following Sun Wukong to guess the names of the dishes.
He thought that if he was lucky enough to guess the dish names, he could take the freshly made dishes back with him. If he was unlucky, he would just shamelessly ask Sun Wukong for the leftovers. After all, they were leftovers, and Sun Wukong probably wouldn't refuse to give them away.
To his surprise, the sneaky plans they had carefully made came to nothing. The dishes they had long been dreaming about were all devoured by that little thief, leaving him utterly unable to swallow his pride.
"I've said before, these things are leftovers anyway; they need dealing with one way or another. It's better they eat it, saves me, old Sun, the heartache when disposing of them," Sun Wukong said with a nonchalant smile.
