Allen rushes downstairs to ask Erllen if he remembers what he was told in the previous time loop. After Erllen says no, Allen decides to give up. Ullen tells him that he can make a gadget that will stop the day from repeating. Later, Ullen says that it's almost finished, but he's going to take a break first. Allen then wakes up in the next loop, and they realize that they'll never have time to finish it, since the day keeps getting reset.
Two years later, on the same day, Ullen decides to leave. Allen looks at old photos and videos, knowing that he'll never have new memories. He wishes that he could go back to a different day, and notices his time machine. Bark Man appears, and reveals that he began the time loop. Allen runs upstairs to find Ullen, but he's already gone.
He finds a note from Ullen that says that he's left to go on his final adventure before the universe ends. This causes Allen to realize that this is the final loop. Erllen and Allen try to use their telekinesis on Bark Man, but they're powerless. Bark Man then takes away Allen's powers, causing him to die from everything that would have killed him while he was indestructible.
Erllen also gets his powers taken away, and falls to the floor. Meanwhile, Ullen is in Allen's dad's yard when he gets erased from existence from Allen being gone. Chad finds Bark Man in the Nintendo room, and he tells Chad that he's Allen wearing a disguise. He then overhears Bark Man saying that it's time to destroy the universe.
Upstairs, Chad tells the other stuffed animals what he heard Bark Man say. They begin to disappear, and by the time they get downstairs, Squeaky, Bark Junior, Whatever his name is, Scruffy, and Fluffy are the only ones left. Soon, Squeaky and Whatever his name is are gone too.
Scruffy and Fluffy get to Bark Man, but Scruffy quickly disappears. Finally, Fluffy is gone, but Bark Man hears a voice. Mr. Bag appears, revealing that he can bring people back to life. Allen wakes up, and he teams up with Erllen and Ullen to get Bark Man to take his mask off.
The person under Bark Man's mask is Erllen. Everyone is confused, since Erllen was still standing next to Allen. Evil Erllen (Bark Man) explains that when Allen stopped his past self from being evil, he caused Bark Man's time line to be erased from existence, only leaving him. This caused Evil Erllen to become evil, and created his villain name, Bark Man.
Allen, Ullen, and Erllen team up to send Bark Man to a random dimension. The next morning, Allen wakes up, realizing that it's finally the next day.
