In order to destroy the machine and save DK Island, you must collect Blueprints from Kasplats during the other levels of the game, give them to Snide, and enter Hideout Helm. Depending on how many Blueprints you gather, The Blast-O-Matic will delay from destroying DK Island. If you collect all 40 blueprints, then the timer is delayed by 50 minutes.
 One Extra Thing
King K. Rool is so mad that he makes sure no one leaves the place till the machine is fixed and DK Island is destroyed.
