Banjo-Kazooie: Grunty's Revenge is a Platform Game developed by Rare (and published by THQ) that released on the Game Boy Advance in 2003. The third game in the Banjo-Kazooie series, the title is an Interquel set shortly after Gruntilda's defeat in Banjo-Kazooie but before her revival in Banjo-Tooie. Being on a handheld system, the game is much smaller in scale in comparison to the console entries, but manages to maintain much of the series' trademark style and feel.
After failing to lift the heavy boulder off of Gruntilda, her henchman Klungo builds a robotic body to house her soul until Gruntilda's sisters arrive to save her. Mecha-Grunty then devises a plan to stop Banjo and Kazooie from ever defeating her in the first place; she travels back in time and kidnaps Kazooie to prevent her and Banjo from ever meeting. Unfortunately for her, Mumbo the shaman sees it all happen and sends Banjo back in time to chase after Grunty, foil her evil plot, and rescue his friend.
Sadly, the game came out after Microsoft's purchase of Rare in 2001 and suffered from poor marketing issues, resulting in many fans of the series being unaware of its existence. That being said, even fans that are aware of the game tend to overlook it, while most critics are of the opinion that it's merely So Okay, It's Average.
- Absentee Actor: This is (so far) the only Banjo-Kazooie game where Bottles does not appear. His role is instead taken up by his ancestor Bozzeye.
- Bag of Spilling: This game takes place chronologically before Tooie, so Banjo and Kazooie naturally haven't learned skills like Breegull Blaster and Bill Drill. On the other hand, they also need to re-learn familiar moves from the original game, even basic ones like Flapflip Jump and Rat-a-Tat Rap. This is barely explained (apparently it has something to do with the trip back in time).
- Blackout Basement: Some areas, particularly in Bad Magic Bayou, are too dark for Banjo to explore unless he's been transformed into a candle.
- Big Bad: Gruntilda, as per norm.
- Bubblegloop Swamp: Bad Magic Bayou.
- The treasure-loving little hippo Banjo meets on Breegull Beach is Cap'n Blubber as a kid.
- The game ends with Gruntilda asking Klungo to send a message to her sisters, Foreshadowing their arrival at the start of Tooie.
- Canon Discontinuity: According to Banjo-Kazooie: Nuts & Bolts on the Xbox 360, Banjo-Kazooie and Banjo-Tooie are the characters' only previous adventures. Banjo Land, a museum-themed level from the same game that features several props and characters from the Nintendo 64 games, also has nothing from Grunty's Revenge..
- Fishing Mini Game: The first one has Banjo using grass to lure sheep out of a sheep dip. Later games have a more-traditional usage of fish.
- Flat-Earth Atheist: During the Freezing Furnace level, Banjo expresses surprise at a talking bucket of coal... despite having met plenty of Animate Inanimate Objects in his adventures up until that point (including a sand bucket).
- Funny Octopus: The octopus transformation.
- Good Ending: Achieved by collecting all the jiggies. Banjo decides to call up Mumbo Jumbo and Bottles for a (ill-fated) card game later. Otherwise, Mumbo's time-travel magic goes wrong and ends up creating temporal clones of Banjo.
- Gotta Catch 'Em All: Typical of a Banjo game. There are 60 jiggies and 600 musical notes to find in all. Furthermore, each level has five Jinjos and seven level-specific doodads to find, ranging from baby chicks to gold nuggets.
- Collecting every collectible only changes your star rating on the ending screen.
- Green Hill Zone: Cliff Farm.
- Hailfire Peaks: Freezing Furnace combines Slippy-Slidey Ice World, Lethal Lava Land, and Eternal Engine.
- Haunted Technology: Klungo created Mecha-Grunty specifically so Grunty's ghost could take it over.
- Interquel: Is set between the first game and Tooie, given Grunty's references to her sisters and that she's still trapped under the rock.
- Mad Eye: Bozzeye, Bottles's ancestor. Kazooie often makes rude remarks about it.
- Make Wrong What Once Went Right: Grunty's entire plan boils down to this; by going back in time and preventing Banjo and Kazooie from ever meeting in the first place, she'll erase her defeat at the duo's hands from history completely.
- Meaningful Name:
- Mighty Glacier: The tank transformation. It can shoot a huge projectile that can break steel doors and kills pretty much any enemy in one shot, but can't jump and dies if it falls from any height.
- Palatial Sandcastle: One appears on the beach in Spiller's Harbor. Only Mouse Banjo could go inside, but it contained a maze and a series of switch puzzles.
- Palm Tree Panic: Breegull Beach.
- Port Town: Spiller's Harbor.
- Pre-Rendered Graphics: The game appears to use this.
- Rhymes on a Dime: Gruntilda, naturally.
- Save the Princess: Subverted. You'd think you can't rescue Kazooie until the very end of the game, but you actually get her back in the second level, Breegull Beach. The duo stays together throughout the rest of the game, and most of the moves you learn involve Kazooie.
- The '70s: If Mumbo's happening bachelor pad (sporting lava lamps, tiger skin rugs and a disco ball) and the interior decor of the two houses in Spiller's Harbor is any indication, this is the decade this game takes place in.
- Shout-Out: Mecha-Grunty's chest plate looks quite a bit like Darth Vader's.
- Speaking Simlish
- Status Quo Is God: Being an interquel, everybody ends up in more or less the same spots as when the game started.
- Underground Monkey: Very common due to the system's limitations. Different Gruntling colors indicate varying levels of strength. Bad Magic Bayou and Freezing Furnace also have recolored Bigfoot (possibly Skunk Ape, due to the marshy setting) and Yeti enemies.
- You No Take Candle: As usual, Mumbo talks like this. And not only if he refuses to transform you into the Candle.
