His jealousy of Ranger Smith and his betrayal, which was triggered by Mayor Brown. He put up warning signs of deadly animals all over Jellystone in order to sabotage the 100th birthday celebration, but nobody saw the signs. Mayor Brown says that Ranger Jones can never be head ranger if the celebration was a success. Ranger Jones told Yogi Bear and Boo Boo that the celebration was lame and that they need to come and spice it up. Yogi started to water ski in front of a large audience with help from Boo Boo, but Yogi's cape caught on fire and the celebration was ruined. Jones was happy that he sabotaged the celebration and was even happier that Mayor Brown fired Ranger Smith and made Ranger Jones the new head ranger. Ranger Jones was a terrible head ranger and did not do any real ranger work. He pointed out that people would come from miles to see the Frog-Mouthed Turtle, so Mayor Brown decided to kidnap it. Jones figured out what Mayor Brown did and that he was tricked, so he gave Yogi, Boo Boo, Smith, and Rachel a ride to the press conference. He lost his position as head ranger and became a random ranger again.
