Stink Moody, family brain, brings home a report card that isn’t perfect? Yikes! Time for him to get into fighting shape and beat back that U for Unsatisfactory in gym! A scan of the sports channel leads to a knock-out find: world-class thumb wrestling, with tricky moves like Snake in the Grass and Santa’s Little Helper (no equipment needed, save for a tiny terrifying mask to sit on your thumb). But when Mom and Dad are not wowed, Stink gets another idea: he’ll kick and punch his way to a yellow belt with the help of a Dragon Master, a seeing-eye Moose, and a mind as still as a pond. Can you say Crouching Tiger, Hidden Thumb? Hee-ya! Ha! Ha! Ha!

Stink puts his letter writing skills to the test when he complains about a jawbreaker that did not break his jaw - with surprising results. He gets sent a huge box full of sweets! But he's so intent on getting freebies that he forgets his best friend's birthday. No wonder Webster's stopped speaking to him. Stink puts things right when, with some help from his Dad, he surprises his class with a pinata using all the free sweets - and decides that while freebies are good, friends are even better!


史汀克決定測試一下自己的書信寫作能力，他想寫信投訴，因為他買的「下巴脫臼糖」並沒讓他的下巴脫臼。不過這卻讓他得到了一個意外的驚喜──滿滿一大盒的甜點！但因為他一心一意都在想要如何得到免費的禮物，反而忘了好朋友的生日，這也難怪韋伯不再與他說話了。但史汀克決定找爸爸幫忙，將得到的甜點全裝入皮納塔，並帶去班上給同學一個大驚喜，總算讓韋伯原諒了他。於是，史汀克學到了一課：免費的禮物固然好，但朋友更好！
