At a Wednesday night, Ollie was being transported by a delivery truck to a local aquarium. Roger Baxter's abstracted driving startled the truck driver, causing Ollie to fall off and get lost. He wandered through the city, until a downpour washed him into a storm drain beneath Littlest Pet Shop. While being chased by sewer alligators, he escaped via a pipe that led him to a tub inside the shop. He ate some fish food he found, leaving puddles at the floor in the process.
The following morning, Blythe slipped at one of the puddles and Russell found an empty fish food container, wondering about the cause. And at Friday, Blythe found another empty fish food can and some chewed on fish toys, to which Mrs. Twombly jokingly suggested that could only be logically explained as caused by ghost. Later, Mrs. Twombly asked Blythe to clean up strange seaweed at the fish food section.
During the night, Russell heard a creepy squishing sound coming from the same place, where Blythe found more puddles. She then followed the puddles across the room to the tub, which was wet.
Vinnie was startled after stepping on a squeaky fish toy, which caused him to knock down the pile of fish food cans. Both him and Sunil were then grabbed by tentacles, making them scream and draw the attention of Russell, who believed the dark figure to be a "sewer-dwelling, hedgehog-eating reptilian ghost". A glow-stick collar revealed it was Ollie atop the fish food cans. He introduced himself and told everyone his story.
After the lights came back, Ollie took part at their sleepover, having tons of fun with a round of My First Formal Dance and showing to be excellent at making balloon animals. He confessed he only came out at night because he was scared of being seen.
Blythe promised to have Mrs. Twombly to call the aquarium in the morning to come pick him up.
