<P> An energetic monster of a boy...blond red hair, popped blue eyes and a dedicated troublemaker, in other words the kid next door...genius in his own way, he makes toy guillotines, full size racks, threatens to poison his sister, can turn himself into a Mr. Hyde with an ordinary chemical set...his voice is hoarse...is sometimes allowed an occasional cigar . </P> <P> When the characters were given names for the television series, he was originally going to be called "Pubert" (a derivation of the word puberty, possibly a reflection of his age) but it was rejected as it sounded too sexual, and the name Pugsley was chosen instead . (The name Pubert was later used when Gomez and Morticia have a third child in the film Addams Family Values .) The Lurch Files' Addams Family Tree lists Pugsley's middle name as Pubert, probably as an homage to Charles Addams' original suggestion . </P> <P> In the American television series, Pugsley is played by child actor Ken Weatherwax . This incarnation of the character is more jovial and inventive; he displays outlandish engineering skills, including the invention of a disintegrator gun, an anti-gravity gun, and other devices . He and Gomez created a computer named Whizzo and a robot named Smiley (played by Robby the Robot). Pugsley and his younger sister Wednesday often play together, rarely exhibiting signs of sibling rivalry; they share an interest in spiders, dynamite, guillotines, and other dangerous "toys ." </P> <P> In an early episode, "Morticia and the Psychiatrist", the rest of the family is concerned that Pugsley is engaging in behavior they consider "odd": wearing a Boy Scout uniform, playing with a puppy, etc . When sent to a psychiatrist, Pugsley tells of boyhood incidents involving hangings, machine guns, and grenades, with no clue that others might find these accounts unusual . </P>
