Max, Rex, and Zoe discover a meteor crash in a nearby forest, and some strange tablets and a card that are used to summon a Triceratops who later named Chomp to come out. Dr. Z plots to become Dinosaur King and a dinosaur battle ensues between Chomp and Terry the Tyrannosaurus Rex (that belongs to Ursula). Soon Chomp is worn out and tired and it seems obvious that Terry will win the battle until Max uses a move called Electric Charge.
