Monoykus is a small insectivore that that appears during The Giant Claw.
Mononykus is a small raptor that was quite possibly the most unique. It had a single claw that came out towards it's feet. Due to this hunting was never it's primary strategy as it foraged for bugs.
During the first night Nigel was awaoke by the Mononykus who attempted to eat his scropion. Nigel gave in and they left.
