He sells a variety of beverages, including milk and root beer, and is shown putting five cents into the Kantina's piano to play a song. It is not known where Hopalong lives; he could be staying at the Dead-Eye Inn. His name is a parody of Hopalong Cassidy, a fictional cowboy created by author Clarence E. Mulford.
Similarities to Squidward
Hopalong is very similar to Squidward (his descendant) in appearance, but he has a handle-bar mustache and wears a vest as well as a brown shirt and a bolo tie. His attitude is very similar to Squidward's: like his descendant, he thinks that SpongeBuck (SpongeBob's ancestor) is annoying and sees Western Mr. Krabs as cheap (similar to the way in which Squidward feels about the modern-day Mr. Krabs).
