Blueprint

"This isn't a game, Kong! Those blueprints are vital to us both, so please go and find some."

- Snide

Blueprints are the design plans for the Blast-o-Matic from Donkey Kong 64. They are collectible items that the Kongs must recover for Snide. There are forty Blueprints in total.

Aside from Hideout Helm, every area in the game, including DK Isles, has five blueprints, one for each Kong to collect. Every blueprint is guarded by a Kasplat, whose hair color and blueprint color corresponds to a specific Kong (yellow for Donkey Kong, red for Diddy Kong, purple for Tiny Kong, blue for Lanky Kong, green for Chunky Kong). If an incorrect Kong is active, the Blueprint appears in the form of a hologram, and the Kong cannot collect it. Each Kong can individually visit Snide's H.Q. with their recovered blueprints, where Snide rewards them with a Golden Banana for every one they return.

Blueprints play a somewhat critical role in the final level, Hideout Helm, because Snide uses the blueprints to delay the Blast-o-Matic's countdown timer by a minute per blueprint. By default, the timer starts at ten minutes and can count down from 50 minutes at highest, if all 40 blueprints were collected beforehand.

Blueprints are required for a 101% completion, albeit indirectly via the Golden Bananas Snide awards for turning them in. The blueprints themselves don't add to the completion percentage. Additionally, by recovering every blueprint, Snide allows the Kongs to replay most of the Bonus Stages from a sub-menu at his headquarters.
