Once, Dr. Robotnik used his Ultra Freeze-O-Matic to cause a blizzard over the entire Mount Splatterhorn to freeze Sonic and Tails who were camping there. Sonic soon after fought Scratch and Grounder, who were under the effects of Robotnik's Servitude Chips, on the mountain, only for faults in the chips to cause Scratch and Grounder to defect to Sonic and help him. Sonic subsequently found the Ultra Freeze-O-Matic and stopped Dr. Robotnik's scheme to freeze everyone on Mobius and install Servitude Chips into them to control them.[1]

  • Rock bridge: An archway between two cliffs that served as a bridge. Due to its weak structure, it eventually collapsed.
