In "War and Pieces," the first of three spine-tingling tales, Marge, worried about the effects of excessively violent video games, encourages Bart and Milhouse to give wholesome, classic board games a shot. The best friends discover that board games aren't boring after all when they find themselves playing a real-life game in which they must beat all the challenges before they are allowed to return to home. The supernatural spells continue in "Tweenlight," when Lisa becomes smitten with a mysterious new student, Edmund, who also happens to be a vampire. When a romance blossoms, the young lovers run away to Dracula-la Land, leaving Homer to come to Lisa's rescue. In the final frightening fable, "Master and Cadaver," Homer and Marge set sail on a romantic second honeymoon, but are interrupted when they rescue Roger, a castaway who escaped an attempted poisoning on his ship. Convinced that Roger is sabotaging their getaway and plotting a murder of his own, Homer and Marge take matters ... Written by Fox Publicity

In "Tweenlight", Dracula mentions that when Lisa becomes a vampire she'll be immortal, so Edmund is too since his father said "you'll both be eight forever". However he later says to Homer that he remembered Edmund from a baby, sleeping in the daytime and checking he was still not breathing. How then can Edmund be a vampire from a baby if a vampire doesn't age? See more »

Great THOH,Tweenlight best of the night,
15 November 2010 | by lesleyharris30See all my reviews

Treehouse Of Horror 21 is a great Simpsons episode,guest starring Hugh Laurie and Daniel Radcliffe.

In War and Pieces,Marge wants Bart and Milhouse to stop playing all their video games so they decide to give board games a go,but after playing a possessed board game all the other ones come to life.

in Master And Cadaver,Marge and Homer go on a boat for a second honeymoon and find a stranded man (Hugh Laurie) who ran off a boat after nearly getting murdered by the host while the rest of them got killed,but Marge and Homer start to believe that he is the true murderer and is trying to kill them too.

Then in Tweenlight,Lisa meets a new kid at school called Edmund who is a vampire,and the two fall in love,but the two fathers aren't happy about it.

next up there should be a Tweenlight saga:blue moon.
