Jehol, Eholo, Holop, Olopt, Lopte, Opter, Pteru, Terus, Ethan, Ryan, Ursula, and Sam are twelve Jeholopterus. They are Dr. Cockroach's ninth creature, and his third Move Card Creatures.
Their card winded up in Mexico. It was found by the man the team saved from Swift. He sent it to the team.
This Move summons them. It has never been used.
They have the exact same colors as the Anurognathus Dozen, with the only difference being slight differences in body structure and the fangs.
