Summery
Mako's seal, Sidney bites a lot of beings, making them believe he has a disease.

Plot
One day, Squidward tries to relax, but Mako's seal keeps invading his yard. And he's constantly bouncing a beach ball on his nose and throwing it around. Soon enough, he attempts to keep Sidney away by building a splintery wooden fence around him, but to no avail. As he complains to Mako about this, Sidney bites him. Squidward asks Mako if Sidney has had all of his shots, and he says that he has, until Patrick comes along and asks him if Sidney has been vaccinated for "Mad Seal Disease," a disease that turns anyone bitten by the afflicted into a zombie, which Mako says he has not. Suddenly, Sidney runs off and starts to bite everybody in sight. Confused, Mako talks the the Miner Trains about the disease and they claim they never heard of such a disease and tell Mako to find Sidney while they get some answers. Equestria is sent into a state of mass hysteria and destruction, and soon, almost everybody has been bitten and turned into zombies. Those who have survived the disease are hiding out at Sharky and Mako's arcade pizza parlor. Mako tries to get in, but they believe he is a zombie and will not let him in, until he slips through the doors.

And Morley then suggests that they might all be zombies, and everyone starts panicking. Sidney then comes in, much to the horror of the onlookers, and then Mako tries to calm down Sidney, but is almost bitten. The survivors then decide to kill Sidney. They all surround Sidney but Mako grabs his seal and jumps behind the cash register counter, and fends his seal [his shark instincts kicking] as some of our heroes watch in surprise, then a shotgun blast is heard. The Miner Trains have came in to put an end to the commotion, explaining that the disease is just an urban legend and that the supposed symptoms were all in their imaginations. Then Blythe finds why Sidney was biting everyone, which was a splinter being in his tail fin, from Squidward's fence, which she removes. Mako is happy that Sidney was never disease-ridden and asks if he still loves him with Sidney barking in response. Then the Miner Trains ask who was the one that said Sidney was disease-ridden.

Mako says it was Patrick, and the episode ends with some of our heroes chasing Patrick to get back at him for causing all the chaos and almost causing Sidney to be killed for no reason. Mako at first is confused, but decides to join the chase along with Sidney just for the thrill of the chase.
