|“I had hoped to reach the summit before the moon has risen. The Craglings never miss a midnight snack.”|
|— Garmadon to Wu in "The Royal Blacksmiths"|
Craglings are large, brutish-looking rock monsters that live in the Realm of Madness.
Master Wu and Lord Garmadon traversed through the Mountain of Madness together, making their way toward the summit. However, Lord Garmadon realized that the moon had already risen, commenting that the Craglings would never miss out on a midnight snack. Master Wu and Lord Garmadon briefly chatted before dozens of boulders formed together, which created a group of Craglings.
The group of rocky monsters cornered the two, causing Lord Garmadon to spring into action. The Craglings chased them up the hill, one catching Master Wu and pinning him down. When it opened its mouth to consume him, Lord Garmadon rushed in and destroyed it with a single blow. The two brothers became surrounded, the both of them being reminded of their past battles as a team. Seeing that their weapons would not do the trick, they both performed Destruction and Creation Spinjitzu in order to defeat them.
- Their designs are based on the Geolix and Tremorox rock monster figures from the Power Miners theme, but with dark gray legs and purple upper bodies and arms.
- A nearly-identical monster design is used in Nexo Knights episode 7, "The Maze of Amazement."
- Their name is based on the word, "crag," a type of rock.
