Slappy Squirrel is an elderly, grouchy veteran cartoon tree squirrel who starred in metafictional Looney Tunes cartoons as Slappy, The Slap-Happy Squirrel.
Today, she lives in a treehouse with her cute, perky and sweet nephew, Skippy Squirrel. She often faces old enemies from her past, like Walter Wolf, Sid the Squid and Beanie the Brain Dead Bison. Other situations see her facing common nuisances, like annoyingly perky neighbors like Candie Chipmunk ("I Got Yer Can") and Skippy's emotional traumas ("Bumbie's Mom"). She typically solves her problems with exaggerated cartoon violence. She has even blasted the Warners' annoying new nanny out of Warner Bros. Studio when the Warners could not do it themselves because of their moral beliefs ("The Sound Of Warners"). The music played during the title card of her segments is an excerpt from Antonín Dvořák's "Humoresque". Slappy is the craziest squirrel.
Slappy is voiced by series writer Sherri Stoner.
