|[List of appearances]|
Cranvil was the highly-respected blacksmith of the Crocodile tribe and has forged several weapons, such as the Gronk, the Krank, and the Slugga. He was an expert in making weapons from metals and rocks native to Chima's swamps and was also especially adept at creating flails. He attempted to make each of his flails unique and named them after the sound they made when hitting a solid surface in order to avoid having to spell long words.
- His name is a portmanteau of "crocodile" and "anvil".
