Amethyst Skid and Topaz Pump are rather childish and gullible, and mostly rude, although Topaz Pump is more cautious. so much that they wear their costumes year-round and constantly spread the word of it around. They are gemstone clones of Skid and Pump. Amethyst Skid is Amethyst version of Skid meanwhile Topaz Pump is Topaz version of Pump. They shine like gold, but is there a heart of gold under that hard exterior? People can't tell what they're thinking, since their expression never changes.
