 Fred has a sudden case of allergy sneezing. To cure it, he goes to a drug store to buy some "Scram". However, the drug store owner experiments a drug which can turn a human into an ape. At the drug store, Fred sneezes at the counter where Scram bottles are put, but saw a look-alike bottle where the ape pills are. Results turns out Fred is turning into an ape each time he takes a pill for his sudden sneezing. And the worst can happen when Fred brings Pebbles and the family to the Bedrock Zoo.
