A Cragling is Ninjago Creature, very similar to Large Rock Monsters, such as Tremorox, Geolix, and Eruptorr from Power Miners. They also look similar to the Crystal King from Power Miners. They are made up of large rocks and boulders, have orange eyes, and usually gather in large groups. Sensei Wu and Lord Garmadon fought a large group of Craglings together. Although the Craglings are made of rock, they don't appear to be very strong considering that Sensei Wu destroyed one with a meteor hammer.
