Scrapie
The name scrapie is derived from one of the clinical signs of the condition, wherein affected animals will compulsively scrape off their fleeces against rocks, trees, or fences. The disease apparently causes an itching sensation in the animals. Other clinical signs include excessive lip smacking, altered gaits, and convulsive collapse.
List of Scooby-Doo characters
In the first live-action "Scooby-Doo" theatrical film — where Scrappy played a decidedly negative role, wanting revenge on Mystery Inc., for abandoning him years ago (he was kicked out for continuously urinating on Daphne, being obnoxious, and the final straw was when he tried to vote himself as the leader of Mystery Inc.). When Velma is talking to a guy at the bar who likes her, she tells him that Scrappy was not a puppy, but had a glandular disorder. Although he nearly succeeds in performing the 'Darkopolypse Ritual', which would give a group of demons the power to rule Earth for the next ten thousand years, his plan is foiled and he and his minions are arrested because he underestimated the Mystery Inc. team, inviting them all to the theme park where he was conducting the ritual after they broke up years before simply to make them witness his triumph when he only needed Scooby present, intending to use Scooby's 'pure' soul to complete his ritual. At the conclusion of the film, Velma says that Scrappy's full name is Scrappy Cornelius Doo.
