The only episode he was solo in was Dry Hard which that was his origin story but how come he never had any other episodes with just him in it? Bushroot, Quackerjack, Megavolt, and Negaduck had their own but not poor Liquidator =(
shareHe did have his own solo episode in season 1, "Dry Hard," He began as a crooked salesman trying to sabotage the bottled water competition to try to mate sure that his bottled water was the only brand in St. Canard to be drinkable.
shareI've heard that it was because the makers of the show found his personality too bland to carry whole episodes by himself, but found that he worked well when bouncing off of other characters.
there's no point in being grownup if you cant be childish sometimes!
