Question: In A-Haunting We Will Go Mel Blanc voices an animated cartoon character portrayed as what?

Context paragraphs:
Speedy Gonzales: Speedy Gonzales is an animated cartoon character in the Warner Brothers "Looney Tunes" and "Merrie Melodies" series of cartoons.  He is portrayed as "The Fastest Mouse in all Mexico" with his major traits being the ability to run extremely fast and speaking with an exaggerated Mexican accent and also speaking Spanish.  He usually wears a yellow "sombrero", white shirt and trousers (which was a common traditional outfit worn by men and boys of rural Mexican villages), and a red kerchief, similar to that of some traditional Mexican attires.  To date, there have been 46 cartoons made either starring or featuring this character.

The Lion's Busy: The Lion's Busy is a "Looney Tunes" cartoon made in 1948 but not released until 1950 and re-issued in 1960 as Blue Ribbon Merrie Melodies, written by Tedd Pierce and directed by Friz Freleng.  It features Leo the Lion (who had previously appeared in "The Lyin' Mouse", "Hold the Lion, Please" and "Acrobatty Bunny") and Beaky Buzzard (who had previously appeared in "Bugs Bunny Gets the Boid" and "The Bashful Buzzard"), both voiced by Mel Blanc.  This cartoon is the first time Blanc voices Beaky due to Kent Rogers' death in 1944, and the final appearance of Leo the Lion from Looney Tunes cartoons until "Tweety's High-Flying Adventure" in 2000.

Nasty Quacks: Nasty Quacks is a 1945 Warner Bros. cartoon in the "Merrie Melodies" series.  It was the final Daffy Duck cartoon directed by Frank Tashlin, who is not credited as he had already left the studio for the second time (this time, for good).  The cartoon marks just the second time Mel Blanc receives a screen credit in a cartoon not featuring Bugs Bunny (Wagon Heels is the first), although it's not until 1946 when he's credited for all of his roles at Warner Bros.  Blanc voices Daffy and Anges' Father, while Sara Berner voices Agnes and Robert C. Bruce narrates.

Foxy by Proxy: Foxy by Proxy is a 1952 Merrie Melodies cartoon starring Bugs Bunny and directed by Friz Freleng.  Mel Blanc voices Bugs Bunny and one of the dogs that talks in the short, while an uncredited Stan Freberg voices the large hound.  This cartoon is considered a remake "Of Fox and Hounds" from 1940; in fact, the opening sequence was "borrowed" directly from the original.

Bugs Bunny: Bugs Bunny is an animated cartoon character; created in 1940 by Leon Schlesinger Productions (later Warner Bros.  Cartoons) and voiced originally by Mel Blanc.  Bugs is best known for his starring roles in the "Looney Tunes" and "Merrie Melodies" series of animated short films, produced by Warner Bros. During the golden age of American animation, his popularity increased.  This era led to his becoming an American cultural icon and the official mascot of Warner Bros.  Entertainment.

Penelope Pussycat: Penelope Pussycat is an animated cartoon character, a cat featured in the Warner Bros. classic "Looney Tunes" animated shorts as the protagonist of the Pepé Le Pew shorts.  Although she is typically a non-speaker, her "meows" and "purrs" (or "le mews" and "le purrs") were most often provided by Mel Blanc using a feminine voice.  In the 1959 short "Really Scent", she was voiced by June Foray, in the 1962 short "Louvre Come Back to Me!" , she was voiced by Julie Bennett, and in the 2000 movie, "Tweety's High-Flying Adventure", she was voiced by Frank Welker.  Her first speaking role was in the 1995 short "Carrotblanca," where she was voiced by Tress MacNeille.

Hoppy Go Lucky: Hoppy Go Lucky is a 1952 Looney Tunes short film starring Sylvester and Hippety Hopper.  Like all the Sylvester/Hippety Hopper shorts, it was directed by Robert McKimson.  The episode is based on the book "Of Mice and Men", which was very popular at the time; it features a giant, dimwitted cat named "Benny", who wants Sylvester, whom he calls "George", to help him catch a mouse to "hug and pet."  Mel Blanc voices Sylvester and Stan Freberg voices Benny.

A-Haunting We Will Go (1966 film): A-Haunting We Will Go is a 1966 theatrical "Looney Tunes" cartoon that was directed by Robert McKimson.  As with the other Witch Hazel cartoons, June Foray voices Witch Hazel while Mel Blanc voices Speedy Gonzales, Daffy Duck, and Daffy's nephew.

Slick Hare: Slick Hare is a 1947 "Merrie Melodies" Bugs Bunny cartoon, directed by Friz Freleng.  It parodies the Mocambo nightclub in Los Angeles—in the cartoon referred to as "The Mocrumbo".  Mel Blanc voices Bugs, Arthur Q. Bryan voices Elmer Fudd and impressionist Dave Barry portrays Humphrey Bogart.  When Bogart comes to the Mocrumbo for dinner, waiter Elmer Fudd needs to serve him fried rabbit in 20 minutes— "or else".  When looking in the kitchen, Elmer finds Bugs Bunny, but Bugs is more interested in having fun with the celebrities than being served for dinner.  The title is another pun on "hair", from an era when hair slicked down by oil was a popular fashion style for men.

Mouse Wreckers: Mouse Wreckers is a 1949 "Looney Tunes" short directed by Chuck Jones, starring Hubie and Bertie in their first pairing with the redesigned Claude Cat (an early, primordial version of the cat appeared in 1943's "The Aristo-Cat").  The short centers around Hubie and Bertie's attempts to move into a new home by chasing Claude out of the home.  Mel Blanc voices Bertie and an uncredited Stan Freberg voices Hubie.  The title is a pun on "house wrecker" or "home wrecker", where a house is destroyed, often figuratively, by a single person.  "Mouse Wreckers" was nominated for Academy Award for Best Animated Short Film for 1948, but lost to "The Little Orphan", a Tom and Jerry cartoon which was the fifth Oscar (of seven) given to the cat and mouse team.
