Frobo

Frobo (Designaton: F0-R1) is a rogue Frobot that made his debut in the episode "Fort in the Road". He was accidentally created in an abandoned factory by Sprig after pulling a lever and initializing the production sequence in the Abandoned Factories. After following Anne and the Plantars to Newtopia, he got stuck in a hole on a cliff near the outskirts of the capital of Amphibia. After the Plantars began to make their journey back home, Frobo again pursued them.

In "True Colors", Frobo is destroyed by King Andrias after trying to fight him. But, he is later reactivated by Polly in "Fixing Frobo", with only his head functional.

Appearance
Frobo was a large robotic frog with elongated, gray metal arms ending in slender fingers. His main body consists of overlapping metal sheets with a shiny frog foot sign along the middle. Placed upon his shoulders are brown, darkly shaded metal pauldrons with three metal studs. His head was mounted atop his body via bar extensions, featuring two brightly glowing optics representing its eyes with darker yellow pupils capable of turning red based on his emotions. His mouth consisted of a crescent speaker incapable of moving but allowing minimum speech, however in "Friend or Frobo?" it is introduced that through learning, he was capable of talking to a certain extent.

Personality
Although he was a robot, he doesn't appear to be very smart/intelligent when compared to Earth's 21st century counterparts, as he kept bumping into trees while walking, as seen in "Anne Hunter".

Background
While scouring the "Ruins of Despair" and stumbling into a factory, Sprig activates the factory's robot assembly line, starting the production process of Frobo's creation. After managing to stop the machine by putting Hop Pop's Road Rules in the disk slot, the factory proceeded to explode as the AI deemed Sprig, Hop Pop and Anne intruders and initiated a destruction phase. After the Plantars left the area and continued on their journey, Frobo climbs out of the ruins and watches them before pursuing them himself.

After secretly following the Plantars for weeks, Frobo finally reaches Newtopia, where he gets stuck in a crest atop a cliff on the outskirts of the city in "Lost in Newtopia".

Somehow, he got unstuck sometime during the group's adventures in Newtopia and continued following Anne and the Plantars who were heading back to Wartwood. He eventually caught up to them by the end of "Night Drivers" where his arms can be seen briefly reaching out to Sprig and Polly as they attempt to ride Bessie by themselves.

Eventually he reached them in Wartwood in "Friend or Frobo?" where he was befriended by Polly, who decided to name him "Frobo" based on his appearance and his similarity to a robot from Anne's video game.
