Shaggy has to go see an acupuncture specialist for his allergies but the doctor and his family are being haunted by a ghost from the old country since they left China and arrived in the US. The gang searches around and find out that it is the doctor's younger brother who is the ghost. He feels they should have not left China to come to America.
As it turns out, he was the only person of the Chen family who believed that change was scary, so he really did not want to come to America with the rest of his family.

My father suffered through years of allergy shots to lessen the effects of ragweed exposure. That was an application of science. That was an application of reason. I am deeply offended by the utter stupidity in Robbie Busch's depiction of the greatest skeptics in literature since Sherlock Holmes embracing acupuncture as a means to cure Shaggy's allergies. Congratulations, you've just with one short story negated the entire core of Mystery Inc.
Even putting aside the stupid premise, Busch's story is about as effective as alternative medicine. The motive is ridiculous. The happy ending is ludicrous and does not gibe with what is seen: namely, a fake monster threatening somebody with a needle.
