Episode 4: The Veg-O-Fortress

Sonic and Tails looks for their fourth emerald in a giant mountain. Once they get in, they encounter a robotic snake-like mutated monster named Rexxon and a robotic scorpion that has robotniks face named Scorpius. The heroes and the evil robots fought each other and they were able to beat them. Later, they run into a super robot named Humpty thats trying to stop them from their journey to obtain the emeralds. Not only him, but Robotnik and his sidekick Snively also tries to stop the blue hero and his friend. Sonic knows that he'll just beat Robotnik again as always. But for his surprise, Robotnik has captured the knothole freedom fighters (Princess Sally, Rotor, Antoine and Bunay). Sonic must fight robotnik through a pinball machine while tails fights humpty outside of the fortress as humpty punches tails out of the mountain. Sonic is able to defeat robotnik and saves his freedom fighting friends and tails defeated humpty by spilling water on him. Later on, sonic finds the fourth emerald and also greets sally and the gang back as he never seen them for awhile. But sadly, sally revealed to sonic that the reason tails is with him is because he was playing at the beach until he went surfing and there was a big wave that tails was caught in. The freedom fighters were looking for him since that day before they were captured by the evil docter. Lastly, sonic says goodbye to tails (calling him lil buddy) and leaves him with the group to continue his journey.
