Sharky is a "sharkdog" (a shark/dog hybrid). He is voiced by Paul Hawkins.
Sharky is Annabelle's pet guard dog who defends Annabelle's house with the viciousness (and also the overall appearance) of a shark. Sharky does not speak, but more than makes up for it in growls (though other animal characters such as Eek can comprehend what he is saying, and subtitles are sometimes provided). Sharky typically terrorizes Eek for fun, although occasionally as a reaction to Eek!'s incessant trouble-causing helpfulness. There are moments where the two get along and partner in the plot line, but they happen to be rare. Sharky loves to bite things, mostly mail carriers. Sharky also has quite a bit of skill as a craftsman, he is constantly rebuilding his doghouse after Eek accidentally destroys it. Like Snoopy's doghouse, the interior of Sharky's doghouse resembles a cavernous mansion with several floors and a garage. Sharky has a curious affiliation with firearms and explosives, which often backfires on himself. In many cases Sharky and Eek's relationship follows a subtly satisfying pattern of karma.
