Agents of L.E.A.F.

Agents of L.E.A.F. is the final quest issued to the player by Dave-bot 3000, Agent Rose, Agent Corn and Agent Citron. As this is a purely cutscene-based quest, no rewards are given and the player cannot choose to replay the quest once it is completed for the first time.

Mission descriptions
"Dave-bot 3000/Rose/Citron/Corn has a reward for you for all your hard work."

Dave-bot 3000
Dave-bot 3000 gives the player an Orb of Portals, and explains its purpose to open a portal to one of the three L.E.A.F. agents. The player simply has to open a portal to one of the three agents to finish the mission.

L.E.A.F. agents
The agents congratulate the player for their hard work, and as a reward, give the player another Orb of Portals, as well as allowing the player to access a chest with coins and an exclusive customization item.

If the player hasn't completed quests for all three agents yet, the player will then have to open another portal to find another agent. However, if all three agents' quests have been completed, the player will then have to proceed to Dave-bot 3000, who will self-destruct. Then, the portion of the garage with the car raises up to reveal a secret entrance to the secret lab. Entering the lab completes the mission.

Trivia

 * Even though Dave-bot 3000 apparently explodes in the final case of this mission, Dave-bot 3000 will reappear after the mission and allow the player to replay his quests.
