It has been YEARS since the last Halloween toon - the last full Halloween toon was 2009's Doomy Tales of the Macabre. But the five long years in between was completely worth it - now we have "I Killed Pom-Pom", wherein Homestar thinks he's killed his best friend, and Strong Bad advises him how to cover up his terrible crime (that he didn't actually commit).

Watch it - and see if you can name all of the Halloween costumes.
