Cyclops Mammoths are big blue cyclops monsters that only appear in Crystal Eye Castle. All Cyclops Mammoths in this chapter are located inside the Seeing Towers (both east and west.) They like to launch big cumbersome leaps that land with damaging force. Skylanders can avoid damage by staying away and defeating them from afar.
It is much easier to defeat the Cyclops Mammoth if they remain chained to the wooden pole the contains their powerful pounces to a small area. (So don't shoot the pole!) But if the chain is destroyed, they will not give up while in pursuit. Though some Portal Masters consider the Cyclops Mammoth slow, they have enough speed to catch up with most Skylanders.
- It slightly resembles Leatherback, one of the Kaiju from the movie Pacific Rim.
