When Squidward gets spritzed with plant growth spray, he becomes monstrously huge. SpongeBob and Patrick are thrilled because they now have a giant buddy to play games with. But the citizens of Bikini Bottom are terrified of the monster, and they want him out! When Patrick realizes that he is the only one out of all his friends without a nose, he decides he needs to get a nose, too. At first Patrick is thrilled with all the delightful new smells he can pick up with his super-sensitive nose – until he discovers that there are a lot of bad smells out there, too. Patrick soon finds stinky odors everywhere, even in his friends' homes, and he sets out to destroy them all.
