Snide's H.Q. is the hideout of Snide in Donkey Kong 64. It is where the Kongs can provide him with the recovered blueprints for the Blast-o-Matic, each in exchange for a Golden Banana. It is where the Kongs first meet Snide, who requests them to recover the Blast-o-Matic's blueprints. Aside from providing Golden Bananas, Snide later uses the blueprints to temporarily intercept the Blast-o-Matic from blasting at DK Isles.
When the Kongs give a Blueprint for Snide, he activates a series of contraptions to bring a chute down from the ceiling, which is where the Golden Bananas come down from.
By default, Snide's HQ only provided the Kongs with the option of reviewing the blueprints that they have recovered. The player can press to view the list, or to exit from the location. If the Kongs recover all forty Blueprints, they can unlock another option to replay from a selection of Bonus Stages, by pressing from the main menu. There are seven Bonus Stages that cannot be replayed from the menu: Busy Barrel Barrage, Splish Splash Salvage, Minecart Mayhem, Speedy Swing Sortie, Stash Snatch, Mad Maze Maul, and Stealthy Snoop.
