Rigby somehow gets a futureistic plasma rifle, so he take the team to the future with the sphere time machine to show where he got it, and then they decide to check out other timelines, but run into a past version of Ernie who takes the time machine  and plans to use it to erase our heroes from exsistence. So using Mucker's delorean time machine they travel trought a whole bunch of timelines tryint to stop him and soon manage to send Ernie back to his own timeline, but then end up nowhere. but eventally get home.

It's a mixture of Road to the multiverse, SB-129, Bad kiss, and back to the pilot
