 In an attempt to eliminate this, Klump uses a risky experiment to extract Buddy's DNA from his system, but his plan backfires and results in Buddy manifesting as an independent entity (albeit with some dog-like traits as his genetic make-up filled in the gaps with samples of canine DNA).Klump proposes to Denise, who happily accepts, but Klump gradually begins to lose his intelligence due to the damage his brain cells have sustained as a result of Buddy being extracted from his system.Eventually, he is able to reabsorb Buddy by using a powerful version of his new youth serum to regress Buddy to amniotic fluid allowing him to 'drink' Buddy and regain his old intellect.
