It’s finally happening … Sideshow Bob is going to kill Bart Simpson! Well, sort of. The Fox animated series has no plans on actually killing off the beloved trouble maker, however, Sideshow Bob will finally fulfill his dream of murdering Bart during the “The Simpsons” 2015 “Treehouse of Horror” episode.

The upcoming Halloween special airs on Fox this Sunday, Oct. 25, at 8 p.m. ET. However, Entertainment Weekly has a sneak peek video that shows fans exactly how Sideshow Bob kills Bart before the episode airs -- by shooting him in the head with a gun! And that’s not all. He brings Bart back to life only to have him mauled by a lion. He then flattens him with a truck before turning him into a paper airplane, shredding him in a fan and then incinerating him. Rough day, huh?

As previously reported, “The Simpsons” show writers and executive producers revealed at the 2015 ATX Television Festival in Austin, Texas, in June that a major character was going to die just for one episode.

“As a kid I always wanted to see [Wile E.] Coyote eat The Roadrunner,” EP Al Jean told the crowd, referring to the Looney Tunes characters. “Sideshow Bob will finally do something he’s been trying to do for 25 years cause it’s the Halloween show.”

Sideshow Bob is voiced by actor Kelsey Grammer. He’s been out for revenge ever since Bart foiled his plan to frame Krusty the Clown for robbing the Kwik-E-Mart in Season 1. Sideshow Bob was placed in jail, but has tried to kill Bart every time he’s been released or escaped. Lisa and Bart have always managed to thwart his elaborate plans though.

The new “Treehouse of Horror XXVI” features multiple short stories. The first will feature Sideshow Bob finally killing Bart -- “only to reanimate him.” Another story will focus on Homer after he wakes up with short-term memory loss, while a third will tell the tale of what happens when Lisa, Bart and Milhouse “get super powers from radiation.”
