* AntiClimaxBoss: None of the bosses in this game can be described as remotely difficult, but the last one, Klogg, is a complete joke, and might arguably be the easiest. There's still one level to complete after beating him, though, and it's absolutely hellish.
* SugarWiki/AwesomeMusic: THE WHOLE SOUNDTRACK. It contains rather unique and great songs arranged by Terry Scott Taylor. One may point out Death Garden Jive, EEEEEEEEEEEE!, Musical Fruit and The Lil' Bonus Room (which completely destroys the fourth wall) as good examples.
** The hidden ending song "[[spoiler:Klogg Is Dead]]" also deserves a mention.
* SugarWiki/FunnyMoments: Random skullmonkey plays with a hamster. Said hamster crawls into his skull through the eyesocket and squirms about inside. Skullmonkey enters a fit of panic. HilarityEnsues.
* HarsherInHindsight: The song "The Lil' Bonus Room" features the line "I get residuals for every game that's sold," which in context is an amusing fourth-wall break. But it started to become this when the game entered [[KeepCirculatingTheTapes abandonware]] status. And then turned into full-on FridgeSadness when, in 2022, Creator/WarnerBrosDiscovery purged huge chunks of their catalogue to avoid paying residuals on them.
* NightmareFuel: Joe-Head-Joe is extremely unsettling. Between being a [[UnintentionalUncannyValley realistic]] [[BodyHorror human head]] in a cartoony game, being fought in a stage that's [[WombLevel made of entrails]], and one of his attacks involving him firing his eyeballs from his eyesockets at the player which make slimy sounds, it's as if he was designed to be as creepy and nauseating as possible.
** The monstrous Skullmonkey stalking Klaymen in the Beans cutscene before having its skull melted by Klaymen's bean induced fart.
* UglyCute: The Skullmonkeys. They act how you would expect typical monkeys to behave, but have skinless and misshapen skulls where their heads are supposed to be.
