The time machine appears as a photo booth with a blender on top of it and a cuckoo clock with sausages attached to the back of it. On its side, there is a container of kelp soda connected to it. It was previously a 25¢ photo booth.
The inside of the time machine is small with a bench and a slot where Karen can sit and power the time travel mechanisms; next to Karen is a camera that is still part of the time machine. There is also a slot where one has to insert a quarter to run the machine.
Role in movie
The time machine was built by SpongeBob and Plankton, using different items from the restaurant Taco Haüs in order to get the Krabby Patty secret formula from the past, to stop the apocalypse. It first goes four days into the future, which creates an alternate timeline by accident. In this timeline, they see the town had decayed into a desert wasteland and a Patrick Star#Bearded Patrick who is later revealed to be sitting on top of a buried Krusty Krab. Next, the time machine travels 10,000 years into the distant future of the galaxy, where SpongeBob and Plankton find Bubbles the dolphin in his inter-dimensional spacecraft.
After escaping Bubbles, the time machine goes to the right time and ends up at the Krusty Krab two days before the apocalypse, where SpongeBob and Plankton take the formula and go back to present time in the Krusty Krab to deliver the formula, only to find out he grabbed the wrong secret formula.
