They are successful, but Botila takes the snake to Alcatraz island where it is converted into a Bionobot. The group then go to rescue it, and it is Danny's idea to use their helicopter's backup battery to overcharge the snake and defeat it. They then return home with it to release it into the wild.
News footage of Kong committing crimes is shown on TV, and the group confronts him about it, but it is soon reasoned that Kong could not have done this, with Danny's reasoning being that Kong can't swim, so if he jumped off the Golden Gate Bridge like he does in the footage, he would drown. Danny then has the idea to show the world how nice Kong is,and at the end of the episode Doug Jones does just this by projecting several holographic Kongs and having them dance in the city.

They are successful and the monkeys are returned to the wild.
Danny attempts to teach Kong to do Kung Fu, but his requests for Kong to preform different fighting styles proved distracting in battle. He then accompanies Kong to Alcatraz where he battles several Bionobots and Botila.
Danny tries to get a ball from under a rock, and provides Francisca an unwitting opportunity to teach Kong about levers. He and Francisca then wait in the helicopter while Doug and Lucas rescue Kong. Danny then saves Doug's life by hitting Botila on a pterodactyl with the helicopter, keeping her from killing Doug.
Danny and Amy infiltrate Alcatraz island to rescue a cyborg baby seal from Richard, who sets the Bionobots after them. Kong defeats them, and they receive a distress signal from Doug Jones, which they follow after relocating the seal. They then arrive in the Arctic to save Lucas and Doug, and Danny throws a snowball at Richard, prompting him to try and murder Danny with a laser. It malfunctions, and Lucas takes his brother captive. Kong then attempted to defeat the remaining Bionobots, but had difficulty moving on the ice. Danny then taught Kong how to ice skate, and he was victorious.
