As Wayne left the door open, the chinchilla escapes, and Jonas takes him after finding him on the sidewalk.
After being asked, Tammy finds out that Jonas is at a high school party via social media.
They proceed to sneak into the party, and discover that Jonas gave the chinchilla to Vanessa, a girl he has a crush on.
They are able to convince Jonas to come with them to the roller rink, where they find that Vanessa sold the chinchilla to a security guard for $40.
Club gave the episode a B−, saying, "As it is, “Adventures In Chinchilla-Sitting” has lots of little moments that work, but its story never coheres into something bigger, and its jokes just aren’t hilarious enough to make that fact not matter.
This made it the fifth most watched show on Fox that night, behind Brooklyn Nine-Nine, Family Guy, The Simpsons, and The Last Man on Earth.
